As an owner of Cadillac's 365, 390, 425, 472, and 500 engines, I rarely had any problem with them. They were always smooth and quiet as intended. I also had a 1985 Fleetwood HT4100 and a 1999 Northstar Eldo TC. While I had no problems with those engines, their reputation is well known. I likely just traded them off before they had a chance to fail. Thanks for covering the big blocks :)

A lot of engineering went into making these cars reliable. Back then luxury wasn't about how large of a tv screen you can put in there, but about comfort, ergonomics, ease of use and reliability. A luxurious car was one you could rely on to work flawlessly every time you need it. Cadillac became the synonym of luxury in America in large part thanks to the reliability of their engineering and the level of care that went into making a quality product to last owner's lifetime. And bc Cadillac was a luxury brand with a hefty price tag it could afford to not cut corners, they could afford to make things the right way not just the cost effective way.

I was 18 years old in 1981, I worked for a old timer in a shop as an " apprentice " . One of our customers was a wealthy old timer who at the time owned a 1968 Couple de Ville. I got to drive it 25 miles round trip to the near by town for front tires and alignment . The old timer was an orig owner and the car had 60-70k on it. I recall floor boarding it numerous times ( I probably burnt 6-8 gal of gas in the 25 miles ) and I recall it seemed to have one hell of a roar and a lot of giddy up and go. Not too much after this period of time, the old timer bought a brand new 1981 Sedan de Ville with the V-8-6-4 which I did not get to drive, but I recall he was very disappointed and irritated with the car. So, this video is very cool to see that I got to drive one of the best 472s ever made.... Thanks...

The various GM big blocks were designed for different tasks. The Cadillac was designed for the ability to power accessories, have a smooth idle and a board flat torque curve from 1000rpm and up. That doesn’t make it less of a motor. It was supposed to be reliable and dead quiet under hood, and it was. Certainly one of the best big block designs. I don’t think they were jetted that lean either because an AIR pump allows you to run richer and clean up the emissions on the back side after combustion. Love your picture of the V8-6-4 with the air cleaner lid flipped. Hi Performance mode.

In 2 weeks I'll have owned my 1974 Fleetwood Brougham for 40 years, here in Australia we went metric in 1974, so it's a kilometres car and is sitting at 704,000 kilometres , about 440,000miles. It has just had its engine overhauled & rebuilt FOR THE FIRSST TIME IN MY 40 YEARS OWNERSHIP. with well over 500 foot pounds of torque in "granny" spec these cars have serious punch, over 500 ft lb torque is in modern turbo diesel territory, however this is in a half century old petrol V8 with a spread bore Rochester Quadrajet which was designed to be frugal. Properly set up these give you 15 mpg around town in peak hour & on the freeeway/highway 20+ mpg not shabby at all from an old 8 litre v8 pulling a fully stocked 6 metre long Fleetwood Brougham that weighs in at 3,180 kilos. Owning a 1973 mk4 Lincoln Continental as well, the difference is dirt obvious , in the Lincoln you need to let it kick down into 2nd gear , let it rev & it will then deliver what the Caddy 500 does by flexing your big toe while remaining in 3rd gear, Caddy has effortless punch instantly. REAL WORLD DIFFERENCE:- due to having to work the revs on the Lincoln to deliver same outcome , Lincoln eats fuel at 5mpg in traffic from a shorter lighter car, WHEREAS, Caddy delivers 15 mpg doing same thing, SO in the real world of day to day driving the Cadillac 8 litre engine delivers 10 out of 10 as mega torque, frugal for size and built to be long lasting 704,000 kilometres durability (or 440,000 miles) what current new item gives this outcome ?? None.

The 429 was a fine engine. Our funeral cars and even our ambulances used this engine from 1964 to 1967. Never gave us any trouble. We loved the 472 and the increase of power. I can still hear the sound it made when starting and idling. Our only gripe was their tendency to overheat in traffic when hot and humid outside. This was an issue that continued on into the 500 engines as well. Most annoying thing having to pull a limo or a hearse over to the side of the road and let it cool off while everybody else in a procession sat there fuming------oh-----and the family---------. The 425 was acceptable when the body size changed in 1977. We were surprised that our 1977-1979 Cadillacs ended up being so trouble free. Out 1979's were just about the last Cadillacs we had with any get up and go until 1993-1996. Those were the last of the old Cadillacs we saw in the funeral business.

I have a '69 472 and a '76 500, and I drove them both stock and modified. If you had a bog on part-throttle tip-in, your Quadrajet needed adjustment. Even with only a 4800 rpm redline these engines have plenty of get-up-and-boogie to them. The monstrous amounts of torque available just off idle and their tall highway gears make them both fast and comfortable at speed. They feel like they're accelerating slowly until you look down at the speedometer and see you're into triple digits.

The power on the more detuned ones can be increased somewhat with some easy adjustments and even a few moderate changes. Things like advancing the timing and adjusting the metering help along with installing dual exhaust and a better-flow aftermarket intake. This has been done to my 500 and it’s made a healthy difference. If someone wants to get into it more, higher compression heads from the early years can be installed as well and there are plenty of more advanced modifications and parts created by enthusiasts that can get this engine to 1000+ horsepower for the real gearhead.

He was just west of Palm Springs, and he drove it to a garage, a distance of a few miles. The second time, the water pump blew, and the fan went through the radiator. He drove it into town, again, and had the radiator and water pump replaced. Later he noticed that the oil looked like a milkshake. He decided to give up on it, and I bought it from him. My friend got a used head for it, and had it surfaced. He installed it, and the car ran fine. A little later, I used the car to tow a '74 AMC Ambassador wagon on a large dual axle trailer 100 miles. What amazed me was that with this huge load, the car got 11 mpg. I was expecting about 5, considering that the 2 cars and the trailer weighed at least 10,000 pounds.

I’ve always heard the 455 in the Buick GS was the superior V-8 for the times. I guess it depends on the subjective nature of the specific criteria used to define “best”. During the late 60s and beyond, Chrysler’s Hemi was the power plant of choice for top fuel dragsters.

The mid 1970’s 472 and 500’s were smooth workhorses, but myself and others were quite disappointed with the lack of power for such large displacement. Chrysler built big luxury cars too, but their 440 felt much stronger in any driving situation. Perhaps the target buyer was so old that they never used more than 1/2 throttle. While the 1968 Eldorado lacked chassis refinement the high compression 472 made it a benchmark for Cadillac performance for decades to come.

Not much experience with big blocks, but my brother had a 383 Chrysler Newport he bought used from a local university professor. It was very nice with just a two barrel carburetor. More on this later. This left me intrigued and I always wondered what it was like to drive a 440 Chrysler. I even saw that there was a special cam version of the 440. I just can't imagine what vehicle I would want to drive today that had a 440 in it. I came into a book once that had the formulas in it for calculating carburation needs. Turns out the two barrels had just enough capacity for large displacement engines like a 383 Chrysler or a 390 Ford. A four barrel wasn't doing anything for you unless you were driving with your foot to the floor.

I had a '69 convertible back in the Eighties, while I was in High School. Dad is a very qualified ASE Mechanic and a MASTER of the Quadrajet... We had that car so well set up, it'd actually get over 20 mpg on the highway and at least 15 mpg in town, IF I kept my foot out of it. With a recurve in the distributor and one of Dad's Quadrajets on it, that big old aircraft carrier would just about hang with the then-new IROC Z Camaros and 5.0 Mustangs that the cool kids drove. I guess I never did really appreciate that car as I should have... It was a factory Mauve with the ostrich print, Eggplant Purple interior and white convertible top combination. I happened to do some research on that particular color combination of the '69 Cadillac convertible, and it turns out that something like ONLY 35 or so were built that way. The other standout things about the car, were that it only had about ten thousand miles on it when I bought it... And it was originally owned by an infamous Houston doctor's wife before he allegedly murdered her. Anyway... I drove that car for about six years and then sold it to buy an extremely low mileage 1960 Dart Phoenix two door hardtop... Damn if it wasn't pink and had full power and A/C... And it turns out that those are as rare as hen's teeth, too. And that one's another that I should have known better about.🙄

There is something so beautiful about these big beefy workhorses, so smooth but yet so strong and usually over engineered enough to not be able to hurt themselves. But it really depends on what the definition of "best" is. Reliability when operated "responsibly"? Fuel mileage? Power and performance? Smoothness? Low emissions? In my opinion, the LS1 fits that bill. Considered LEV in some states, capable of 33 mpg cruising at decent highway speeds (67-70 mph seems to be the sweet spot in a Firebird), a reliable workhorse when operated as designed and unmodified, smooth but potent revving up to the 6200 RPM rev limiter without obvious signs of going breathless... and of course seems to operate the same regardless of whether it's arctic or arid temperatures out. There's a reason it kept reaping engineering awards for years following its intro. It's the only GM engine I've ever had where at 24 years of age there is still not one drip of oil from a seal, nor a puff of blue smoke at cold start-up. And all with a straightforward proven and simple layout (OHV, single cam, no multi stage intakes, no cylinder shutdown, etc). The SBC probably comes in a close second, on sheer versatility alone (and the high RPM crank vibrations of the 350 being addressed with 4 bolt mains where appropriate). Nonetheless the LS1 was such a leap ahead that other brands fell behind for what seemed like close to a decade. Even at idle the 32V Ford 4.6 would drink fuel as if the tank had a puncture, while the LS1 could idle for hours without budging the needle on the gauge. Perhaps the 5.7 Hemi from Chrysler would be the first to match the LS1 in operation many years later but suffered from some weak points early on (valve seats etc) while requiring some kludges to be emissions compliant (twin spark plugs, with 30000 mile change intervals, etc). Again, I still enjoy the HECK out of my Pontiac "big block" :) as well as my TPI SBC and I'm certainly enjoying my 2016 Hemi (which I find is so much nicer than my previous 2006 version) but that LS1... at 24 years of age I'm amazed at how it simply has not shown any signs of aging (including some track use early in its life). A true engineering marvel.

The best "American" engine of all time, is unquestionably the 32 valve, quad cam, LT-5, that powered the 1990-1995 ZR-1 Corvette. Now "American" may be a bit generous, as it can be argued that it was developed in heavy collaboration with Lotus, However the performance records the LT-5 still holds to this day, cannot be argued with..........100 miles @175.600 MPH........500 miles @ 175.503 MPH..........1000 miles @ 174.428 MPH........5000KM @ 175.710 MPH......5000 miles @ 173.791 MPH......12 hour endurance @ 175.523 MPH.......24 hour endurance @ 175.885 for 4221.256 miles.............world records irrespective of class...........5000KM @ 175.710.......5000 miles @ 173.791 MPH..........and finally 4221.256 miles @ 175.885 MPH.........this is from a stock 350 CI production engine that routinely delivered 25+ MPG, and also routinely passed the "nickel balance test" for smoothness. these records are insane, and the ZR-1 Corvette beat the previous records that were held for 50 years and were done with a special built Car the Mormon Meteor that had a 1570 CI Aircraft engine in it! While these Cadillac engines are great, they are not remotely in the same class as the LT-5. the Cadillac Northstar was based heavily off of the LT-5, and is a great engine also, but it was not hand built as the LT-5 was, and suffered a problematic oil leak that was very hard to deal with, because of ironically a very durable skirted block design.

With mild modifications to the exhaust ports the 472 and 500 can be made to scream. Plus Edelbrock does make a Performer manifold for that engine. While the stuff is not forged on the internals they're sufficiently durable enough based on their mass and density such that they should hold up fairly well. And moreover be capable of considerably more power output than their Factory rating necessarily would indicate. Add other aftermarket goodies like a gear vendors Overdrive and it would make a quite budget-friendly Highway Cruiser other than The Upfront cost of the overdrive unit. I know when my dad had his 72 Coupe DeVille it got regularly about 16 to 18 MPG on the highway, I know at least one individual running a gear vendors overdrive behind the th400 with a 500 swapped in of all things in a sedan DeVille and they get over 20 MPG on the highway, compression is still mild enough for pump gas but it does breathe freely thanks to some exhaust work and better intake probably Edelbrock, but I know they're still running stock Quadrajet.

The 472 and the 500 blocks are very popular with airboat people because you can get a lot of hp & torque to turn the propeller at low RPM. I believe the 472 is the first engine design to have the air conditioning compressor integrated in its initial design instead of tacked on. As a weird bit of trivia I think in 1969 there are only 12 Cadillacs made with the air conditioning delete.

It's amazing that it took so long to adjust to getting power from engines at lower emissions levels using unleaded gas, but I'm sure glad that it happened. There's an interesting story behind the use of the lead additive. They say that anyone alive before 1980 has some degree of lead in their bodies. There are even studies showing a reduction in violent crime corresponding with the phase out of leaded gas. Now we're at the dawn of electric propulsion they'll probably find issues with being exposed to such strong electrical fields, maybe?

Well I'm glad that they're the engine of choice if you're a Cadillac collector to have because I have eight of them in my collection. And one Oldsmobile Seville.

My '57 Coupe De Ville has a '75 Cadillac 500 motor with Edelbrock intake, properly set up quadrajet and no air pump or AC. Tip in is perfect.

Agree the 472 was excellent. The previous 429 had a few issues so not one of my favourites. I would rate the 460 as an excellent engine also.

Sitting less than 10 feet away from me now on the other side of the wall is our 1980 Cadillac Fleetwood Brougham D'Elegance with the 368 engine..same firemist blue color and wire wheel covers as the '80 Coupe DeVille featured in your video. In addition to being the last (non V8-6-4 Caddy big block), it was also one of the latest appearances of the Turbo 400 transmissions in a GM passenger car. My family had two of these Cadillacs resting side-by-side in the garage for decades...one was the above-noted '80, and the other was a 1979 Cedar Firemist Fleetwood Brougham with the 425. The 425 was definitely the stronger of the two cars, as expected. One notable memory happened in May of 1980 following the eruption of Mount St. Helens here in Washington State. That eruption bathed us in ash; so much so that many drivers affixed aftermarket outside auxiliary air cleaners to their vehicles. We continued to drive the '79 (incidentally without any of this supplemental equipment) until one day when I discovered that a dealership service tech had mistakenly left the air filter element out of the air cleaner housing during the previous service job performed just prior to the mountain blowing. At that point, we were nearly 3,000 miles later and approaching the next service date. We were, of course, shocked and not happy. Nevertheless, that engine lasted another 350,000 miles without incident.

My first car was a '70 Coupe deville. That 472 was smooth. The throttle response at around town speeds was intentionally soft given the age of the average Cadillac buyer. But crack open the back barrels on the Quadrajet and bye-bye 460 Lincoln! Super reliable car except for the points. Always carried a spare.
