In the history of the automotive world, Cadillac has always been different and known to bring extraordinary stuff. As a luxury automaker and a trendsetter, it always delivered some “first-ever’s” on the market. Cadillac was the first one to introduce a mass-produced V8 and then the first OHV V8, both setting new standards. The reputation as the “Standard of the World” had been received for a reason.

The Cadillac 472/500 cu in engine displacement was reduced to 425 cu in in 1977, displacement was reduced again in 1980 to 368 cu in.

You're absolutely correct, especially about the commercial chassis lasting 3 years longer than the passenger cars.

Bragging rights: You have the biggest engine in the neighborhood, and... 2. Something that approximates an electric motor. Very smooth and lots of instant torque. It is rare for a traditional Cadillac engine to rev above 3500 rpm. I laugh when I see old Cadillacs with growling V8 exhausts; Cadillacs were SILENT. You weren't supposed to know it was even running. It just oozed down the road, kind of like a boat moving down a canal. Modifying one of these for performance gets VERY expensive very quick, if you can even find an aftermarket part.

@Terraceview Год назад

All the people saying it could make XYZ power but heads suck etc... they were made to have huge torque at very low (1500-3000) rpm. To make them "fast" defeats the purpose. I much prefer one of these beasts than any new whiny turbo engine. It's basically a truck engine in a very big car, awesome!

My parents had a 1976 Cadillac Eldorado with the 500 V8 in it, and it was bulletproof as far as powetrain. My grandparents drove Lincolns exclusively and the 460 was smooth, quiet and powerful as well. For my money, the best of the GM big blocks was the Pontiac 455. Overall, the Chrysler 440 was probably the hardest to beat. Ford's 460 definitely held its own well.

@@captain1334 WHAT? No. You cannot build a Cadillac V8 to the same cubic inch or power as the Big Block Chevy for the same price. There are NO aftermarket blocks for the Cadillac. So other than a 0.060" over bore or 0.100" on an excellent block and maybe a custom crank your are not getting many more cubes out of the old Cadillac. You can easily make a 502 Chevy for cheap with a junkyard block. Or you can start with an 8100 (496ci) and throw a cam at it and make more power than a 1970 500ci Cadillac. It will also last longer and rev higher thanks to the far superior oiling system of the Big Block. Don't get me wrong though. I would much rather see Old Cadillac modified to make big power under the hood of a classic rather than a Big Block. But the reason Big Blocks and Small Blocks (LS/LT included) are so popular is because they are cheap, plentiful and well supported.

If memory serves, I believe it was Cadillac who first used the pedal layout we all know now, with the clutch on the left, brake in the middle, and throttle on the right. Before that, pedals were like switches - in whatever order manufacturers decided to position them (a common layout before this was to have the throttle in the middle and the brake on the right.) Not sure exactly why other manufacturers copied this layout, but it soon became ubiquitous.

The 1960s and early 1970s was a different era long before fuel economy requirements. That was the time when an automobile manufacturer wanted more power and torque, they did not do 4 valves a cylinder and no overhead cams and no turbochargers or superchargers. Instead for more power and torque automobile manufacturers such as Cadillac used a huge displacement, gasoline thirsty V8 engine. And this V8 engine powered a large, heavy, land yacht car that gave a quiet, smooth and comfortable ride. Those days are long gone.

By american standards , the 472/500 cu inch Cadillac engine block , is a compact design externally. The design is much closer to being a small block in it's dimensional size , rather than a true big block, when measured next to any of it's contemporaries, i. e Lincoln 462, the Ford 385 series , or Chrysler 413/ 440 RB. Even the second generation AMC V8 , although a medium sized block , is in there. The really big (!) block's physically by sheer visual presence, would be the Mopar Hemi's and the 429 FoMoCo BOSS , thanks to their wide head assembly. By far the LARGEST engine block I've seen in any automobile, would be the Lincoln 430 , of the late 50's. It's just HUGE.

Same here. I’ve had several 69-70 Coupe Deville 500s over the years before the values started going up. A lot of people don’t understand how powerful the early 500ci equipped cars are. Especially in the lighter Coupe Deville and Eldorado models. They definitely make low end torque, but they could also outrun a lot of muscle cars on the interstate back in their time. Its one of those cars that just keeps going once you get on it. Only thing to me that ever compared was the ‘69 Mercedes 300sel my mother owned when I was a kid. It had the big 6.3 fuel injected V8. I only ever rode in it but it felt similar in a lot of ways.

@DucknCoverin Год назад

He’s speaking figuratively. The 500 was the end of the big block era of going bigger and more powerful. None of those other engines are over 500ci. The modern usage of big blocks was relegated to trucks and heavy duty fleet vehicles. Neither GM, Ford, or Mopar have offered a passenger car with a big block since the 70s. No manufacturer since Cadillac has offered anything larger than 500ci in production car, and never will for obvious reasons. That’s what he means by this being “the end of the old big blocks”. Just like the early 70s was the end of the muscle car. There have been later vehicles that you could call a muscle car, and there’s been a revival of big horsepower cars from manufacturers that attract a niche market, but the muscle car era itself ended decades ago.

The TH425 automatic (reverse rotation for Eldorado driveline) had been rebuilt for higher shift points firmer shifts and the entire ensemble installed in an unassuming '66 Corvair. I was tempted a couple times to link the "4-8" switch to the throttle but decided against it. I feel it should be operated as an 8 full time and only switched it to 4 on the highway. I didn't want to mess up my shift points, how much vacuum the power brakes wanted etc etc etc. Couple times I pulled the trans into manual low and put it in 4-mode and creeped along in traffic jams. Seemed to run cooler and had adequate power for that.

@patrickshaw8595 Год назад

@@geoffmooregm Yes realize the intake manifolding of all ordinary classical V8 engines was "middle two cylinders on one bank plus outer two on other bank" connected up to one throat of a two barrel carburetor (or to one primary + one secondary barrel of a 4 barrel). So no airflow through left side of carb? No fuel gets pulled out those barrels. The distributor doesn't care that every other spark plug is dry and not lighting anything. Caddy's system fell down because it was paired with immature computer technology. Would have worked great on pre-smog engines. But gas was so cheap then that nobody wanted to buy a more expensive big engine to save some fuel. They just bought smaller engines - usually in smaller cars. Also - disconnecting the valves from the camshaft is easy with ("pushrod") Over Head Valve engines. It's pretty hard with Over Head Cam engines. And since gas got expensive nearly every thing is Over Head Cam now. Just in case you are interested I am thinking about how easy/hard it would be to adapt to Buick and Olds V8s. Looks easy ! With some work I think it can be done to Pontiac V8s as well. MAYBE to a small block Chevy. It definitely can NOT be done to a big block chevy or chrysler Hemi.

Umm in the custom engine building world they have already taken Cadillac 500 blocks, slapped ls9 heads onto them and have put down well over 1200 hp, 1500 foot pounds of torque. Back in the late '60s early 70s drag racers used to take these Cadillac 500s, drop them between the rails of an old model A or model T, port the heads out by hand or swap them for some Ford big block heads and they were running the quarter mile around the 11 second mark

also at the cost of reliability and drivability. A 300hp turbo 4 cylinder you're gonna be waiting for turbo spoolup for the torque to kick in, 300hp big block you have that power already on tap from idle. It's all a compromise

They have turbo inline 4’s with 300hp that last 200,000 miles with 30mpg. What more do you want? Yes they don’t sound great, but they’re quiet and torquey off the line, turbo cars aren’t what they used to be, they have boost immediately now and plenty of top-end.
