Lift is critical, but not what defines how "big" a certain camshaft is. It's more about how long you hang the valve open.. not how high you lift it... awesome video Uncle Tony. 👍

The camshaft rotes at half the amount or, "speed" of the crankshaft. Normally when referencing, "degrees" they are crankshaft degrees, not camshaft degrees.The degree wheel mounts to the crankshaft. The more aggressive, or quickly the valve opens, the heavier a valve spring usually has to be to control valve float at the same RPM and faster hydraulic lifters open valves, the heavier valve springs have to be to prevent lifter pump-up at the same RPM. There is advertised duration, 0.050" duration and there is S.A.E. duration. With hydraulic lifters S.A.E. duration is usually at 0.006" lift, opening and closing sides of the cam lobe. Some camshaft makes use a lower lift for a higher advertised duration number. Some car makers use a different opening lift with a different closing lift when computing advertised duration. Before 1964 the car industry standard for hydraulic cam lobes was to make cam lobes that had a 0.050" lift duration that was 70% of the SAE 0.006" lift. This for acceptable wear. Around 1962 the aftermarket and industry engineers were trying more aggressive cam lobes. Around 1962, Iskenderian Racing Cams promoted high performance hydraulic camshafts with more aggressive 75% cam lobes. The 0.050" duration was 75% of the SAE 0.006" duration. In 1965 Pontiac changed all of its 4 barrel and tri-power carb camshafts to75% cam lobes, with the two barrel carb engines staying with 70% cam lobes.Pontiac may have tried that with the 1964 GTO camshaft too. The 1964 GTO camshaft was the same part number for GTO engines and on paper was the same as the 1964 4 barrel automatic transmission camshaft, BUT IT HAD A DIFFERENT PART NUMBER! In 1965 Chevy had the 350 horsepower 327 and new 396 engines with 75% cam lobes. In 1966 Ford had the 390 GT and Olds had the limited W-30 camshafts, for the new 75" cam lobes. The 1967 Dodge 440 Magnum still used 70% cam lobes, but the 1968 340 went with 75% cam lobes. "Theoretical" maximum power happens with the camshaft degreed with the intake centerline at 106 degrees ATDC, REGARDLESS OF LOBE SEPARATION, but this is just theory, as is, maximum torque happens with the intake centerline at 102 degrees ATDC, regardless of lobe separation. These theories are usually very close with, "correct" sized camshafts. The closing of the valve is limited by the mechanics of the valves slamming against the valve seats. The intake valve runs, 'cold" and can take fast slamming to be noisy. The exhaust valve runs red hot and is more easily damaged and must be closed more gently. Modern computer designed hydraulic cam lobes are even more aggressive now and some are designed to prevent lifter pump up at higher RPM with less valve spring pressure, but the really aggressive camshafts make more power and their cam lobes still require the heavier valve springs.

Another benefit to roller lifters, beside reduced friction and wear at initial break-in, is that if you try a radical ramp on the lobe, it can try to push a non-roller lifter as much sideways as upwards, which causes binding inside the lobe bore. Mopar adjusted this by using "fatter" lifters and bores, meaning the diameter was wider than other engines, so a Mopar cam can get away with a faster ramp before it needs the heavier roller lifter. Other engines would use a "mushroom" lifter that had a wider foot or base on the cam lobe to have that increased diameter benefit. The sooner you push that intake valve to full lift--assuming the valve springs can handle it--the sooner that full lift occurs during the duration the valve is open. If you ported the head to flow best at full lift, did an angle valve job that also works best at full lift, and the valve is unshrouded at full lift, this means the valve is performing longer during the duration, at the lift it was designed to work best at. But what if the duration of time the intake is open (from its moment coming off the seat to full lift and back onto its seat again), extends into the time the exhaust valve is open? That is overlap. Too much, and you have emissions issues, low vacuum for brakes, and rough idle. But if you increase the ramp speed, ie, the intake valve pushes open to full lift sooner due to roller lifters or an increased diameter of the base of the lifter, now you can decrease the entire duration (from lifting the valve off the seat, to getting to full lift, and returning it to the seat again) but not lose (or lose much of) the amount of time the valve is at full lift. It would be as if you only had a mile of pavement to travel, and you want to spend as long as that distance at 100mph as you can. The car that accelerates to 100mph the quickest, is the one that lets you enjoy 100mph for as long as you can over that 1 mile of pavement before the car has to come to a complete stop. That's where the expense of a roller lifter setup and springs to handle its weight come in handy. But there's a case for not designing your intake port and valve to work its best at full lift. During the duration, the valve sees full lift once, but partial lift twice--once when the valve is opening, and again when its closing. some designers like to work on mid valve lift performance for that reason. So, now you have the basics, the terminology, and now you have some philosophy :)

Excellent explanation! There are so many #s on cam cards that it's easy to get confused, especially for those who don't have much experience. To me, the 3 most important #s are advertised lift,050" duration and LSA. You explained them in language that's understandable. Last summer, I was at a local car show and one of the participants was really talking up his engine. He used a term that I hadn't heard in YEARS when he said it had a 3/4 cam. Now, I know what a 3/4 cam is and, in my experience, they're not all that great. You should've seen the "deer in the headlights look" on his face when I asked him what a 3/4 cam is.

@@phoenixrising4573 Basically, a 3/4 cam is just slightly bigger in lift/duration than an "RV" cam. An RV cam is meant for low end torque and mid range power. The rpm range is usually from idle to around 5k give or take a few hundred. A 3/4 cam is usually designed for more mid range power while still trying to keep as much low end torque as possible. Their usual range is about 1500-5500 rpm give or take. An RV cam usually has advertised lift/duration #s around 260 degrees and .450 lift. A 3/4 usually has #s around 280 degrees and .480 lift or so. Keep in mind that these are advertised #s. The name 3/4 race cam was used for decades.

I really enjoy your content and the way you explain things that are both "mandatory" and "not mandatory" and myths. I am new to your channel, but I would love for you to take a survey of which engines people want to build from scratch to stock specs, and do a series on the winner of that survey, and build it from scratch, just to stock specs to get it running on a bench. All other adjustments for various applications can be covered either by you, in a separate video, or a channel that you would recommend for that purpose. I would really love to watch that, no matter the winning engine (even though I am a Ford guy), because I love the way you explain things, and your passion for this stuff. You remind me of my engine-building teacher in college, that got down deep into this stuff, and gave physical examples of various things, to make us truly understand every nook and cranny of building an engine, including details like, heating gasoline in a beaker and putting a sample of each stage of heating into a glass tube and lighting it, to demonstrate how the different "octanes", and the way they burn. I'd like to see everything, from 'cylinder honing" to using feeler guages and that green string that you use to measure tolerances for caps and bearings, micrometers, small hole gauges, calipers, etc.., pre-oiling and preparing the engine for "first-start" and "break-in". I know that this would probably need to be a "sponsored" video, but I am just showing my interest. Regardless of whether it happens or not, I will still be watching. :)

a solid lifter camshaft has "quieting ramps" on the lobes that take up the slack in the valve train before and after opening/closing the valve. keeps that hammering of the valve train to a minimum. hydraulic cams do not need that(no slack in the valve trane). If you just put solid lifters on a hydraulic cam the valve train will hammer badly. if you put hydraulic lifters on a solid lifter camshaft the valves will start opening sooner and close later. Never tried that but know of people who wrecked the engine with solid lifters on a hydraulic cam. what I have done successfully is to not push the hydraulic lifter piston way down in. reduces pumping up a bit. example on chevy if it calls for half a turn in on the adjuster give it less than a quarter turn. you can run the hydraulic lifters with minimal initial lifter compression. hopefully you will get around to these things. love your videos. knowing this we understand why letting collapsed hydraulic lifters clack away and not fixing that will result in hammering of the valve system, fix it.

"Camshaft Duration is the measurement of the time one valve begins to open until it finishes closing. Duration is measured in degrees of crankshaft rotation, not camshaft rotation. You'll see duration specifications at .050 inches. Cam manufacturers agreed on a standard to measure duration so all cams are measured the same way. The idea is to measure duration starting at .050 inches of tappet (lifter) movement. As the lobe lifts the tappet up, when the tappet moves .050 inches, the duration is measured from that point. "

Just to split hairs. Duration @ .050” is measured at .050” tappet lift, not valve lift. Excellent video, I experiment with a lot of cams. For me my major experimentation started getting serious after buying into marketing bs leading me to purchase a comp cams xtreme 4x4 cam for the 350 in my k5 blazer, with the wide 114* lsa the engine idled like stock, but had lousy throttle response, non-existent low-mid range power. So I then bought a comp 280H magnum, with similar lift and duration figures, but a 110* LSA and being a straight grind, my lame 8:1 goodwrench crate 350 now had a steady lope, instantaneous throttle response, and enough low rpm torque to light my super swampers up. So then I went to an isky mega cam with nearly identical lift/duration to the previous cam but it was ground on 106* lsa, now my engine had a nervous crackly idle, crisp throttle response and even more power from roughly 2500-6000 rpm. But gas mileage dropped off a bit. I’ve been playing with cams ever since. Not just in sbc either. Small and big block mopars , ford Lima, ford Windsor, ford fe, and 305, 307, 327, 350, 377, 383, 400, 406 sbc’s. I might have a bit of a problem.

Thank you. Had a general idea of what a camshaft does but not to its full extent in tuning an engine.

On the base circle, I was intrigued when I saw a modern engine where that part of the cam was narrowed. Perhaps for less friction, you don't need as much path width to keep the lifter in place.

If it was a modern engine, it probably had roller lifters. Old cam lobes are ground with a taper to keep the lifters rotating, hence x amount of friction is necessary.

It’s not “path width” to keep the lifted on track. It’s the amount of width necessary for the lifter to follow the ramp profile. Look at Pro Stock cams. Among other interesting features, they have narrow lobes and bearing journals. Roller cams with roller cam bearings don’t need as much surface for the bearings and with a roller following the lobe, that can be narrower too.

The type of engine you are talking about has no lifters, push rods, or rocker arms. There just flat cam followers. You are correct about the reason for the narrow base circle being for less friction. Just like low tension rings, every little bit helps.

Great video. I’m running mid 10’s with a 351-W with a mechanical flat tappet on a 100 shot of nitrous. Chet Herbert CJ4N camshaft. Very simple setup.

Thanks for beginners advice Uncle Tony, However I've had a great idea!....can you do separate video for proper newbies like me starting from the very beginning of which car to pick and choose for restoration projects, tools you need, skills you need, finance you need, what courses you need to take at local training school's ie welding, body panel classes.... Cheers mate Gavo from London!

Awesome Ty Tony ! In my big block Chevy oval port .. I got a aggressive sounding cam . Low vacuum on the brake til I blip the throttle to stop .. dead hooks then . But at @45 mph on a 3.25 gear she sounds like a boxer jogging the punch bag . At a stop light with solid mounts. She tosses around like a Harley.. it was awesome till the intake gasket let go again.. so I hoping the cams fine because I did a quick turnaround on the driveway and the next morning she was cappachino... 🤷♂️. First catch before start but still had to tear it down to make sure. This time I’m getting a drill press and safety wiring the header and intake bolts Hoping it last longer then before 🤷♂️

I got a .258/.268 duration .501/.524 lift, 112lsa in my 360 Magnum. Those lift numbers are with the 1.6:1 Magnum rockers. I originally bought this cam for a 318 LA roller engine (when Mopar went to TBI in the late 80s they went to roller cam) so it went into my 360 Magnum. I did check the lifter to dog bone clearance, don't need to break the lifter retainer plate, and wipe a lobe.

We broke a lifter at the track a couple of years ago. I’m no engine builder but my car owner swapped out the cam in less than an hour without a degree wheel. I watched him do it but I still don’t know how he did it but I was impressed. Ran a 5.60 next pass . Didn’t look hard to do but dam you could tell he had don that a few times

Good info. I have a hard time explaining cams sometimes. I think I use numbers too much in my explanation. So I end up confusing people. I will try to do it the way you just did.

Measure your lift, measure your base circle. Take the lift # and subtract the base # that gives you a # let's say it's .350 that's your lobe lift take your .350 & × it by 1.5 if your rocker ratio is that then you get your valve lift which would be .525 lift. Just an example for anyone who didn't understand

I'd join up with that cult and I'm a GM guy! You can't beat common sense and experience! For the most part, engines are engines, they all react the same way to modifications. I'm referring to common, every day stuff here, not "exotics" like Chrysler Hemis and SOHC Fords etc.
