Greetings...Arn Brown..............Thanks, for the nice comment, and for watching too...............Well, I only have 4 Videos so far, in this Series, for the LARGE distributor Cap HEI/High Energy Ignition type of Distributor................There are a few things to keep an eye on, some of which, include the condition of the distributor Cap's (inside) metal Terminals, as well as, the condition of the Rotor's metal Tip, as in, the High Voltage, that Arcs between those metal parts, that I just mentioned, will usually (electrically) Erode/Wear away, in relation to, how long the engine is actually running, time-wise, that is...............The spark plug Wires, usually last quite some time, but, it's a good idea, to replace the Set of them ("One" at a time, so things don't get messed up), when they have accumulated lots of use/mileage..............Also, don't let the spark plugs, get too many miles on them, before installing New ones, especially if, they are the Conventional type of spark plugs, that usually have the Larger center Electrode on them, cuz, the LARGER the spark plug Gap gets, due to, all of that High Voltage, electrical Arcing/Erosion, between the Electrodes, the more Demand/Strain, that will be imposed on the Ignition Coil.............So then, if You have any questions or concerns at all, just post a comment or two, and I'll try to help You out................You might also find, that, some of my other Videos, on my KZitem channel...RockysRoadshow...might be of some help to You as well...enjoy...and.......till next time........Be Safe, take care, and have a good one.

Thanks for a great video I inherited a 1976 GM 1 ton dump truck from my dad. My dad is still alive but can't drive anymore because he's legally blind lost his eyesight but he still rides in the passenger seat. And the truck has this type of distributor I am in the process of replacing the spark plug wires to see if that helps with the once in a while missing cylinders so it backfires a few times once in a while as it's running especially going down hills and it has a cherry bomb exhaust muffler on it so I can hear the engine and you can hear when the cylinders start working again because that stops making a certain sound and I've gotten used to that sound it sounds more like it has more power and you can definitely hear the difference. Not sure exactly but it's funny that when the exhaust is extremely smelly with fumes of partiallyburnt fuel it seems like the cylinders are working better. It seems like that would be the other way around when there would be fumes it wouldn't be firing but I don't really understand it and I could totally be wrong I'm just going by the sound it makes that it sounds like it's making more power but I really don't want to spend thousands of dollars on getting this fixed at the moment. Because it does run and I use it a lot and runs pretty well for what it is it seems to miss more in the cold. She is 40-year-old truck I call Her BIG RED :)

Greetings...Ben Boudreau............You're welcome, and, thanks for watching too...........Sorry to hear about your Dad, but, from what I recall, is that, when a Person (unfortunately) loses, one of, His/Her senses, then, that, in itself, will probably make it so, that, All of the Other (working) senses, tend to become much more sensitive, or alert, if You will, oh, and, maybe, You have already noticed that already (I'll bet).............So then, with that said, I gotta do my best, in helping You out, with gettin' that 1976 GM 1 Ton Dump Truck, runnin', much better, that it appears to be runnin' currently, or your Dad, will surely notice..............There are quite a few things, that can cause, just about any gasoline burnin' engine, to, shall we say, not run so good, and/or, not run, very smooth at all............Something like, Water/Condensation, in the Gas Tank, or maybe, something, as simple as, a "Dirty" Air Filter, that sits on top of a carburetor, will Restrict, the amount of Air, that enters the top of the carburetor, and if really plugged-up/dirty, then, too Rich, of an Air/Fuel ratio/mixture, it will usually end up being, along with, less miles per gallon, as well............The Fuel system, has to be in good shape, as in, things, like, the Fuel Filter, not being plugged-up/restricted...carburetor Choke/flap, has to be Fully Open, when the engine is fully warmed up-to Operating Temperature, cuz, if it's Stuck-On, even just a little bit, then, that will also, Restrict the amount of Air that enters the top of the carburetor as well, which also = too Rich (air/fuel ratio/mixture)...........The Ignition System, has to be in very good shape, as in...having the correct Spark Plugs, that are reasonably clean, and the Electrodes, not being worn too much, as well as, having the Gap, between those two Electrodes, set/adjusted, to the "Specification", for that Exact engine/vehicle (might be .045"...as in...Four-tee-five thousandths of an Inch, which is a really common Gap size, for the LARGE/Cap HEI/High Energy Ignition, type of Distributor), oh, and, just be aware, that, some spark plug Types/Designs, are Not Gap-able, so, always check that out, so Ya don't Damage those Exotic, Pre-Set Types...........When-ever a spark plug Gap, gets...larger...and...Larger...and...LARGER...due to wear/mileage, then, the poor ole Ignition Coil, has to output, much More/Higher Voltage, measured in, Thousands of Volts, in order to create a Spark, between those spark plug's Electrodes, so Don't let em get too BIG, or, too many miles on them, as well............The Newer/better quality, the spark plug "Wires" are, the less chance, there will usually be, for any Miss-Firing, of the spark plugs, most of the time............It's always a good idea, to keep "All" of the spark plug Wires..."Away"...from each-other, and, "Away" from, any Metal parts & pieces, such as Valve/Rocker Covers...Exhaust Manifolds, and the like, cuz, that High Voltage, that travels through those spark plug Wires, sure likes, to Jump out of those Wires, and find the easiest way to an (electrical) Ground source, especially so, if the spark plug Wires, happen to be, the inexpensive/economy/cheaply made type, and/or, if, one or more of them (in the set), are perhaps, just plain, worn out.............The distributor Cap, and the Rotor, that spins around inside of it, have to be, in very good condition, and also, be Moisture-free, inside of the Cap as well, so as to avoid any miss-firing of the spark plugs...........Being "Very Careful", Have a look, at the Running Engine, when it's "Dark" Outside, for any "Sparks", that might be showing-up, where they "should-Not-be", cuz, if You happen to see, any...Un-Wanted...Sparkin' go-in on, then, that, my Friend, could very well be, the cause, of an ignition (system) related Miss-Fire, I be thinkin'.............So then, maybe, check out those things above, and hopefully, some of those things, will help You out some-what..........If You care to, You can let me know, how it's going.............Good luck, and........till next time........Be Safe, take care, and have a good one.

+gruntmachinegunner Greetings gruntmachinegunner....Thanks for watching, and, Thanks, so much, for what You had to say, about this HEI Distributor series of mine.........Yes-Sir-ee-Bob, I do plan, to not only take this HEI Distributor "Apart", but also, hopefully, shall we say, Spill-the-Beans, on how this thing actually works, along with, some of the things, to be watching out for, that, may very well, cause a Problem or two, as in, parts, that might have too much wear, as well as, things to be aware of, during assembly, or installation, of a new part or two...................Now then, about "Shimming" the Clearance, to take up some of that excessive Slack/Clearance, between where, the Helical Drive Gear, almost meets, the bottom end of the HEI's Aluminum Body.................Due to the Expansion Rate Differences Between Aluminum & Steel, as in, Aluminum, will usually Expand/Grow More, than Steel does, for a given length..............Pretty much meaning, that, when the HEI's Aluminum Body (and the Steel shaft as well), gets Heated-Up, to Engine Operating Temperature, then, the Clearance Between the HEI's aluminum body/housing, and the Helical gear, would probably become Less, as in Less (length-wise) Clearance, between the HEI's Aluminum Body, and the Helical Gear (and yes Boss, that Shim, or Shim Stack, will probably be, between the two).....................I was thinkin', not so long ago, to just have the HEI's, Distributor Body/Housing, with (no cap & rotor, no vacuum advance, no module, no pick-up coil...etc.), the Steel Shaft (No weights and such), and the Shimmed Helical Gear Installed, with the roll pin, without any other Parts, and, put it in an Oven, heated up-to, not sure, maybe 400 Degrees Fahrenheit maybe...???...(make sure Your Better-Half is not Home...!!!...lol), and now, this Guy, is Using Her favorite Oven Mitts (looking side to side, so as Not to get Caught...!!!), so He doesn't Burn His Hands, when He takes the Pizza...oops, He meant, His, Baked to Perfection...(partially assembled) HEI Distributor...outta the oven, for a Clearance Measurement, Between the HEI Distributor's Aluminum Body, and the Helical Gear, but, gotta be like...Jack-Be-Nimble-Jack-Be-Quick...and no, Not the Candle Stick, but rather, take a Quick Measurement, probably with a Feeler Gauge or two, in order to take, that, damn irritating, I Just Gotta-Know..."Hot" Clearance Measurement...Test result...damn-it....!!!...lol .............. I probably wouldn't have any less than, oh, about .015" (Fifteen Thousandths of an Inch) "Clearance", Measured at Room Temperature, there-abouts, Between the Helical Drive Gear, and the HEI's Aluminum Body (and yes, the "Shim, or Shim Stack" is Between the two at this time), just in case, that HEI's Aluminum Body Expands "More" than the Shaft does, and, I be thinkin', if not enough Running Clearance (length-wise, that is), when Hot, then some, shall we say "Seizing/Galling", might take place, where-by, having the Shaft, not being able to Turn Freely, and, as it should be.........................I might Not, "Shim" the Clearance in this particular HEI Distributor...Say What...!!!...lol...well, seeing as how, I saw, an Already Established, nice, smooth and shine-ee "Wear-Pattern", on the Drive Side of the Helical Gear's Teeth, I'm thinkin' that, if I were to Disrupt, that already established Gear Tooth "Wear-Pattern", by introducing that Helical Gear, be it Up or Down, from the Center of that Helical Gear's already established Gear Tooth Wear-Pattern, in relation to, the Camshaft's Helical Gear, I figure that, I might end up do-in more Harm then Good, and besides, It's only an old Chevy Van, we are talkin' about here anywayz (as opposed, to a, I wanna Rev that there Racing Engine, just short of self-destruction...!!!...lol)....Shimming is one thing, but, You have to be very careful, so as not to impose any Force Downwards, onto the Oil Pump, as that is a very unwanted Problem, all in itself, so, make sure that, there is a bit of Clearance, when You Pull Up, and Push Down, on the Stationary, Top part, of the Distributor Shaft's, Plate, (that is welded?, to the actual steel shaft), where the Advance Weights and such reside, once the HEI Distributor, is installed in the Engine....There is usually a Gasket/also wanna be Shim, that usually goes Between, where the HEI's Distributor Body, meets the Chevy Engine's, Stock/type of Intake Manifold, who's Thickness, if selected correctly, will provide that much needed Clearance, that takes care of that, I don't want any Force Downwards, on my Oil Pump...........................If, and when-ever taking an HEI Distributor Apart, notice, that, there is usually a "Dimple", partly Drilled into the Hub, on the Helical Gear, and this "Dimple", has to Line-Up, with the Rotor's Metal "Tip", cuz, if it Is-Not, in Alignment, upon re-assembly, a Nightmare, it just might be...Yikes...!!! (and that my Friend, is due to the Odd Number of Gear Teeth, on that HEI's Helical Gear).........................I'll just mention one last thing, before I depart, and that one thing is................Make sure, when-ever, Mounting an Ignition Module, to the inside of the HEI's aluminum Body/Housing, to have the Mounting Surfaces, of, both the HEI's Aluminum Body/Housing, (where the ignition module mounts), and the bottom of the Ignition Module, super Clean, and, use some "Heat Sink", Heat-Transferring, Specific Paste, that's formulated, for that Specific Purpose (No Die-Electric Grease/Goop Allowed...!!!...lol), so the Ignition Module Doesn't "Over-Heat" and go Kaput, as in Poof, need a new one now...!!!.........oh, and also, those 2 Mounting Screws, are pretty much the (electrical) Ground, so make sure, that they are Clean, as well as, the Metal Holes, that You see in the ends of the ignition module, are also Clean.................Always Discharge, any Static Electricity, that You may have stored up, in Yourself, by touching, a cool, and not moving, Metal object, as, that, quite Powerful, Static Electrical Charge, has been known to Destroy Electronic Chips...!!!...................Well, there You have it, for now that is, and........till next time..........Be Safe, take care, and have a good one.

Thank you for the excellent video and explanations. I am searching for testing information on the Tach signal on an HEI distributor. It seems as though my signal is not pulsing, therefore pegging the needle on the gauge. Also when setting the meter too RPM mode the signal sends the digital reading to "out of limit" Any comments would be most appreciative.

Greetings...Arrow-Mountain Diesel.........Thanks for watching.........Well, from what I recall, is that, the HEI Distributor's Tach Signal, outputs, quite the high voltage "Spike", alright...........There is, what is called, a..."Tach Filter"...or, in some cases, it might be called, a..."Tach Adaptor"...that, shall we say, absorbs this, not wanted or needed, excessive high voltage "Spike"..."Before"...it make its way, to a Tachometer..........This, full strength, high voltage "Spike", can sometimes "Damage/Destroy" a Tachometer's electronics, that wasn't designed for "it", especially so, if it wasn't protected, by having that, so called Tach Filter/Tach Adaptor in place..........Some time ago, I've actually seen, a mid 1970's/1980-ish, aftermarket manual's, schematic diagram, that shows, the Tach "Filter", in the ignition circuit, that's placed, between, the ignition coil, and the tachometer...........If you need a Tach "Filter", then, there should be, a few choices out there..........I kinda doubt, that you'll be able to get a hold of, a New General Motors unit, but, you might find, a good/used one, somewhere on the internet (EBay maybe...???)...........There might also, be a Person or two, that custom makes these things, and hopefully, for a reasonable price as well...........Maybe, a high performance/go fast, automotive performance business, can get one, maybe..........If you are good with basic electronics, then, the Tach "Filter", is quite easy to make (as in, DIY)..........From, what I recall seeing, is that, all it takes, to make one, is just..."2 Resistors"...and..."2 Capacitors" (electrolytic type?), with the correct...values/rating/tolerance...and, arrange those 4 components, in the correct circuit arrangement............Try doing an internet search, for a..."Tach Filter"...or, a..."Tach Adaptor"...for an...HEI Distributor, and see what that produces for Ya..........Good luck, and......till next time.......Be Safe, take care, and have a good one.

I have a 305 SBC with mild cam. my module blew and replaced it with a bwd. now I'm losing spark at 3000rpm. I have 14v into coil, and 815ohm at the pick up coil. would this be a sign of a faulty module. I thought I'd ask before dropping $$ on a delco replacement module.

Greetings...C_Spidey Cosplay..........Thanks for watching.........Here are a few things, for you to consider..........Make sure, that You "Apply", a thin coating of..."Heat Transferring"...Specific...grease/paste like compound (Not the Die-electric stuff...!!!), onto, the Ignition Control Module's, metal/back-side, so, the quite a bit of Heat, that the Ignition Control Module generates, as it is operating, gets "Transferred" to, the mounting Pad, that's on the inside of the HEI Distributor's aluminum Body, which, kinda acts like, a, shall we say, Heat-Sink...or..."it" (the, ignition control module), has the potential, of Over-Heating, and getting damaged............You can usually find, the "Heat Transferring" Specific, grease-like compound, at a computer, or electronics store, and some folks, will usually be, putting it on, (high heat producing) CPU's & GPU's, that are found in things, like, computers and gaming consoles, etc...(just get the cheaper stuff, b-cuz, some of the high-tech brands, can get quite expensive...!!!)...............Also, make sure that, both, the Metal/back side, of the Ignition Control Module, and, the HEI Distributor's (aluminum) Mounting Pad, are Nice & Clean as well (before installation)............Also, those..."2-Holes/Metal eyelets"...that go through the Ignition Control Module, and the 2 (mounting) Screws, have to be Clean & Shine-ee, b-cuz, these items, happen to be, the Ignition Control Module's (electrical) "Ground" (very important)...........If...???...the "Pick-up coil", is very old, sometimes, there can be a small break, or (intermittent...???) bad connection, in one, or maybe both of, those 2 Wires, that are connected to the pick-up coil's (very fine wire) windings, and, it might be possible, that, when, the Vacuum Advance is activated (if using one, that is), then, it will move the pick-up coil assembly, in a circular fashion, and, when it does, those 2 pick-up coil Wires, get bent/flexed, a countless number of times, while driving...........A good clue (to me, that is), is, if the plastic-like insulation, that is on those 2 pick-up coil Wires, is kinda hard, and not as supple/flexible, as that, of a brand new pick-up coil assembly, then, all bets are off/no guarantees at all............To test for any Breaks/Bad connections, just simply, connect the Ohm-meter's probes, into/onto, the pick-up coil's Connector (while disconnected from, the ignition control module), and "Wiggle/Bend a bit", those 2 Wires, and watch the Ohm-meter, for an Open circuit, or any, moving ohm values, possibly..............Make sure, that, all of the HEI Distributor Parts/components, are the "Correct" ones, for your "Exact", HEI Distributor, as in, Ignition Coil, primary and secondary, ohms/resistance values/specifications, and that, the "Correct" pick-up coil, is used/installed, as, there are a few of them, and, the "Colors", of those 2 Wires, are a pretty good clue, to be watching out for...........Make sure, that, all Connections are super Clean, and, if there happens to be, a (sheet) Metal, (electrical) Ground-ing Strap-like thing, that is supposed to be, the (electrical) Ground, that usually, gets pressed against the ignition coil's (outside) laminations, due to the mounting screws pressure, well, keep it super Clean too, oh, and, which, by the way, is usually hidden, under, the Big HEI Distributor Cap's...(top) Cover/Cap, where the ignition coil, the carbon resistor button/contact, and that quite large, rubber-like, insulating washer, are all, hiding as well..............Also, try not to, rule anything out, as, sometimes, fuel system problems, might behave like ignition system problems, and, the opposite way around as well.............If you are still having problems, after checking out the above, just let me know, well, if you care to, that is.............Good luck, and.......till next time.......Be Safe, take care, and have a good one.

Greetings...rhshel..........Thanks for watching..........Some of the HEI (High Energy Ignition) distributor parts, should still be available, as in, I think that it's called a "pole piece" (that be, the outer set of triangles, that have the pickup coil, mounted inside of it.........The Cap and Rotor are easy to find........Ignition coil, no problem.........Vacuum Advance canister/unit can probably be found (just make sure to get the "Correct" one, as there are many different specifications for them, as in, the vacuum rating in Hg/inches of mercury, which will affect, when it's actuating rod, starts pulling, and also, when it reaches, the fully pulled in point, and also, the amount of, vacuum advance, timing degrees, that it will provide, as well)..........There are "recurve" kits available (some good, others, not so good), that could have, advance weights, and a selection of colored springs, that have different tension specifications, as well as, a pretty good instruction sheet (of paper), that will show some graphs, of the different timing advance curves, and what springs to use, to match the graph, that you want..........Ignition Control Module, no problem.........The worst wear point, will usually be, those two pins, that stick up through, those two mechanical advance weights, and, if the pin wear is really bad, then, probably won't, provide the advance curve, that it was originally designed for.........Parts prices will add up to, being quite a bit, so maybe, check out the following..........D.U.I. (Davis Unified Ignition, I think), in the USA, will custom make, a brand new HEI Distributor, for most of the engines out there, stock, or modified..........They take all of your vehicle's, and engine's information, then, they set up, the ignition advance curve (weights & springs, probably on a distributor machine), for your "exact", vehicle and engine combination, which will probably result in, having an engine, that has the best power, and fuel economy too, well, if Ya can keep Ur Big Foot, from mashing down on the gas pedal, that is...lol..........They also have some pretty impressive spark plug wires too, so, if Ya care to, check out their website (for free...lol), oh, and, there are probably some KZitem videos as well (just find 'em...lol)...........The older "Smog" HEI distributors, were really holding the engine's potential back (low, slow, and late ignition timing advance, although, cruzin' along, wasn't all that bad, as I recall)..........The, DUI...HEI distributor, also has, higher voltage output, going to the spark plugs, as I recall, and.......till next time.......Be Safe, take care, and have a good one.

Your weights are on upside down in this video if this distributor turns clockwise. This is confusing me looking at the weights like this. They are installed for a counterclockwise distributor to be able to swing out and advance your timing.

Greetings...Don Hirtle………...Thanks for watching...…...Yes-Sir-ee-Bob...I use tah think, the very same thing, even when, I was looking at a picture, of those, HEI (High Energy Ignition) centrifugal advance weights, in an aftermarket Chevy manual, a long, long time ago...…….Are they really installed upside-down (backwards?)….Hmmm, how can that be...???......Well, with the older (up to about 1974), General Motor's, points and condenser distributors, then, the, so called auto-cam, was permanently fixed, (welded?), to the end of, that quite long distributor shaft, that also had those two pins on it, that the advance weights pivoted on, along with those two calibrated (tension) springs...……..Then starting, oh, about 1975 there-abouts, then, that, HEI (BIG distributor cap) electronic type of distributor, came about, kinda making the good ole points and condenser, type of distributors, obsolete, kinda like Dinosaurs...lol (but, I still do like, working with/on, the older stuff, never-the-less)………...The HEI distributor's mechanical advance design, is a bit different, when being compared to, the good ole, points and condenser type of distributor...……..For a V-8 engine, then, the moving around the shaft, 8 point (male) star (reluctor?), slides onto that long shaft, from the bottom, then, on the top side, then, there are, the two centrifugal advance weights, and the two (calibrated, tension) springs...…...On the HEI distributor, the, shall we say, "auto-cam", (also mounted on top), is a separate piece, and can be changed, to a different profile, that has a number stamped into it, for identifying purposes, and is secured to those two upright pins, with two "E", or were they "C" clips (if not, then, call em circlips...lol)…(there are 4 pins in total/on top....2 for the auto-cam, and, another 2, for the advance weights to pivot on)..…...So yeah, the HEI design, is quite a bit different alright, which makes things, kinda look...SDRAWKCAB...(that be...backwards, spelled backwards...lol).........So, if Ya wanna see advance weights, on an HEI distributor, that appear, to look like, they are for, a GMC or Chevy V-8, then, just have a look-see, at an HEI distributor, for an Oldsmobile V-8..."BUT"...just remember now, the good ole Oldsmobile V-8 HEI distributor, spins..."Counter-Clockwise" (or call it, anti-clockwise, if Ya prefer to), that also has, centrifugal advance weights, that appear as though, they were installed "Backwards" as well...!!!...lol...…….Yeah, I know, looking at the direction, that those, HEI advance weights are installed in, takes some time, getting used to, (seeing) alright, but, if Ya have an HEI distributor in your hands, and start moving, the mechanical advance's, parts and pieces, back and forth, then, you'll see, how it works, when being compared to, the good ole points and condenser, type of General Motors distributor...……..Here's how I can tell, which way, that, the General Motors distributors rotate, without, even taking the (distributor) cap, off of it...!!!...…...Just pretend, that you are blowing air, into the "vacuum advance" unit/canister, and there's, a, shall we say, Impellor (kinda like, a water-wheel, inside, under the distributor cap), then, the so called water-wheel, will spin clockwise for a Chevy, and, counter-clockwise, for an Oldsmobile V-8 engine (simple huh), and......till next time...….Be Safe, take care, and have a good one.

Greetings...Rafael Rodriguez........Thanks for watching........Well, I have never worked on your particular year and type of H.E.I. (High Energy Ignition) distributor (with the BIG cap on it), but, I did have a look at a picture of it, without the distributor cap on it, and, I "did not" see any mechanical weights and springs at all...!!!.........Also, I did not see a vacuum advance canister (looks kinda like a little space ship...lol), that usually mounts onto the large diameter, of the distributor's aluminum body (that's just below, where the distributor cap sits, when it's installed) either.........Seeing as how, there "are not" any weights, or a vacuum advance canister on it, then, I be thinkin', that, the vehicle's on board computer (ECU), will be controlling the amount of ignition (spark) advance, at all vehicle speeds, and engine loading conditions, as in, just cruising along, or maybe, while mashing the gas pedal to the floor, possibly.........There's probably only one adjustment/setting, that can probably be made, with the type of HEI distributor that you have there, and, it will probably be, to check, and if need be, adjust/set the distributor's..."Base" (or might be called, initial) timing, and, once it's correctly set, then, the vehicle's on-board computer, will be able to adjust the ignition timing advance, for the correct amount of timing advance, that, the engine needs, at that exact moment, and operating condition too (as in, good gas mileage, and also, good performance too)..........Try to get a good manual for your exact vehicle.........A factory manual, or, an aftermarket manual.........A Haynes (aftermarket) manual, is super good, for a person, that is just starting to work on cars, as, there is lots of information, about safety, tools, and lots of pictures as well, that will make learning about your vehicle, that much easier, and hopefully, it will also show you, how to set your distributor's, base (initial) timing as well.........Good luck, and.......till next time......Be Safe, take care, and have a good one.

Why can’t anyone talk to all the points to the workings of the HEI distributors, I.E. plus and minius wire connections, that the dilemma I’m in is figuring out where the wires go on these modules, my factory plugs are gone, and nothing is marked, thanks BigAl California

Greetings...Al Kennedy.........Thanks for watching........The following should help you out, I hope.........Head over to Rockauto.com, and do a search for your "exact" vehicle.........Once your vehicle is selected, go to the "ignition" tab, and click on it........Once there, you should find a list, of both new, and remanufactured/rebuilt, HEI distributors, that will usually have lots of "pictures", that you can look at, in order to see, what wires, or, wire colors, go to each connection point..........If that doesn't work for you, then, look at some HEI distributor videos, that are on KZitem........Just make sure that, you look at an HEI distributor, that is "exactly" like yours is...!!!...because, some HEI distributor's rotors, will rotate in the opposite direction, as in, a...Chevy's rotor, will rotate "clockwise"...while, an...Oldsmobile rotor, will rotate "counter-clockwise/anti-clockwise...!!! (rotor, rotating direction, can usually be determined by, looking at, which side, that, the vacuum advance canister, is mounted, to the HEI distributor's aluminum body/housing) .........There were different colored wires, coming out of, different HEI pickup coils, as I recall, so, pay close attention to that as well........There are also website "Forums", on the internet, for your vehicle's year, make, and model, where you can ask questions, and, there are quite a few people, that are on those "Forums", that are very smart, and have lots and lots of experience, on just about any topic, that pertains to your own vehicle........So then, there Ya go.......Three different places, where you can go to, and hopefully, at least one of them, will provide the information that you are looking for........Good luck, and......till next time......Be Safe, take care, and have a good one.

Greetings...Jose Pena...…….Thanks for watching...…...I'm not sure, what you meant, by saying...gear one...???...…......So, here Ya go, then........First thing, is to make sure, that, the helical gear, is lined up correctly, with the rotor's metal tip, if, the helical gear, was removed from the distributor's shaft, that is..........There is a "dimple" (partially drilled hole), that's located, not too far, from the hole, that is drilled completely through, the helical gear's hub.........That "dimple", has to line up with, the metal tip, that's on the rotor, before, the roll pin, is hammered into the hub, and distributor's shaft.........If the helical gear, gets installed incorrectly/180 degrees (half a turn) more, then, trouble, it will usually be, because, the relationship, between the rotor's metal tip, and that helical gear, will be out, by, 1/2 (one half) of a gear tooth..........If, your "gear one", happens to be, the distributor cap's...number 1...terminal, then, the rotor's metal tip, has to be pointing at, the distributor cap's, number 1 terminal, when cylinder number 1, is at top dead center, and is also, on the firing (down) stroke.........The (number 1) spark plug wire, has to connect to, this very same distributor cap's terminal, and, the other end, of this (number 1), spark plug wire, has to be connected to, the engine's, number 1, cylinder's spark plug.........The firing order, for a small block Chevy (Chevrolet) engine, is usually...1-8-4-3-6-5-7-2...so, Ya have to know, which cylinder is which, as in, while sitting in the driver's seat, behind the steering wheel, then, starting, closest to, the front bumper, then, the cylinder numbers, are...1-3-5-7...on the left hand side, and...2-4-6-8...on the right hand side.........The spark plug wires, have to be installed on the distributor cap's terminals, in the correct firing order (1-8-4-3-6-5-7-2), as well as, in a...Clockwise...direction, starting with, the number 1, cylinder's, spark plug wire........So then, if the above, isn't, what you were looking for, then, perhaps, tell me, what it is, that you want to know........The more, that you are able to tell me, then, I'll have a much better chance, at being able to help you out...thanks......and......till next time......Be Safe, take care, and have a good one.
