I get so excited when I see you've posted another video! Thank you for your hard work and great videos!

I had a '76 Eldorado Convertible with the fuel-injected version 500. It was a dream to drive; you could watch the gas gauge drop, and you kept your foot to the floor.

All my Italian friends farthers owned that car and what a beautiful car it was indeed..😊

Your videos are always so well done and this one is no exception. Beautiful photos and excellent information. I love it when you post!

The politicians and government who knows more than we do ruined it. Anyone want an EV?

Nothing exceeds like excess !

Beauty!

Standard of the world

I like the Caddies and pretty much any car of this timeframe. Funny thing is I owned a 76 Oldsmobile Toronado (sister car of the Eldorado) with Oldsmobile’s big block 455. It had a 4BBL carb and was rated at 215 HP. This 455 was only in the Toronado and the entire drivetrain was used in the GMC Motorhome.

Superb video! I have owned seven Cadillac's, so I can relate to this video immediately.

So many haters on here. But guess what, none of you have a RUclips site. I love this channel.

Caddy with almost diesel level torque 😅💪🏾💪🏾

That white drop top is beautiful! GIMME THAT CAR!

Cadillac is always the best!

Wow

I was extremely lucky to own a 75 Eldo with this monster. I miss that car. I still brag about owning a car that had/has the biggest motor ever stuck in a passenger car!!

I have been a passenger in a early 1070's Cadillac Coupe and Sedan DeVille and 6 fat guys like me can go accross the U.S. with room to spare and a very large trunk for peoples suitcases.

Those Cadillacs from the middle 1970s also had lots of comfortable interior space to go with that 500cid engine. Though they weren't designed for racing, they could hold their own with most vehicles of the time. I still recall a Sunday afternoon when an impromptu drag race took place with a 1970 or '71 Ford Mustang in the left lane, a 1964 Oldsmobile Dynamic 88 coupe in the middle lane that I was a passenger in, and a 1975 or '76 Cadillac Coupe deVille in the right lane on an avenue in Brooklyn, NY. Truth be told, the Mustang would have prevailed if the cars were on a race track, but the Oldsmobile and the Cadillac each held their own despite the Cadillac easily outweighing both the Ford and the Oldsmobile.

question what about the chevy 502 ??

Having worked on the later 500 c.i. V8, the addition of the EGR valve was detrimental. These engines had big problems carboning up. Removing the cylinder heads and de-carbonizing the engine was a temporary fix. The EGR valve set it all off, starting the carboning problem and creating driveability issues. The addition of fuel injection was a godsend. The last Eldorado convertibles in 1976, with their 500 c.i fuel injected V8 was probably the smoothest running version. With this fuel injection system, also used on the Seville's 350 Olds V8, problems were usually caused by fiddling with them.A popular mod was smashing in the vacuum end of the fuel pressure regulator with a socket. Sure it increased fuel pressure, initially, but down the road it caused the diaphragm to stick causing severe running issues. The secret that escaped many was that you could stick an allen wrench inside the vacuum inlet and adjust fuel pressure that way. Another problem plaguing Cadillacs from 1974 and the rest of GM vehicles from 1975 was the HEI ignition. It produced so high a voltage that it would burn through the ignition rotors. I'd done more than a few road calls to repair stranded vehicles. It took GM a few years to figure it out, but the aftermarket figured it out well before GM did.

What is that awesome music you use at the beginning and at the end?

The 429 was a pretty nice engine too, but it never gets yhe fame the 472 gets

My father had a 72 Sedan de ville with the 472 engine learned to drive in that car, what a torque monster if you into the throttle in 2nd gear you feel it in your neck how hard it pulls

I love the 460 in Continentals, but man is the 500 something. More and more it seems that we will never reach those heights again.

V8 😁👍

1970 & 1971 saw the biggest torque numbers ever in a factory-built engine! Wow, I like these Cadillac big block V8's!!

The 472, 500, 425 and 368 cubic inch V8s were all great engines all were based off of the 472 cubic inch engine from 1968.

My first car I inherited from my grandfather was the 69 coup de ville with a high compression 472, and that thing would pass everything except the gas station. If they hadn't had to compromise the intake design to make hood clearance, it would have been even better.

I don't know if it's still available, but for awhile there was a kit to bolt a 472-500 series engine into GM's smaller cars like the Chevelle and Monte Carlo. Makes sense to me; you could put one of these pre-emission era engines into one of those, and with the engine bone-stock, it would still be a hot rod with 370+ hp and 500+ lbs of torque right out of the gate

Forgot to add to my previous long comment that today you can still find abandoned Caddies with these mammoth 500 cid motors, and they will run like you had only parked the car yesterday. It is an amazingly long lasting motor. I've heard this from people that know. You also pointed it out here.

I knew I had seen "fuel injection" badges on some of these Caddies. Wow, what a step forward, since we had to wait until the mid 80s to finally enjoy the smoothness of an early morning f.i. cold start. Also those older Eldorado brochures drive me wild with those beautiful vehicles featured in their pages. Thank you for taking us back to times we wont see again. Seems that GM's muscle year was 1970, with 1971 a close second.

Cool vid but these AI voiceovers are like nails on a chalkboard

Just bought a 1970 Caddy 500 long block, working out a deal on a 1950 Pontiac Streamliner roller, gonna restomod it with the Cadillac 500ci and a TH400 at the heart of it. Looking like it's gonna end up disc brake converted with a Ford 9 3/8" rear end

It did sort of survive a few more years as the 425 and 368.

So basicaly 1970 is the engine you want with newer EFI swap! :D

How low the Mighty have fallen . . . 😞

I'm surprised GM Hotrodders don't utilize the Caddy 500 more

Growing up, my neighbors had an Eldorado and Delta 88. The old man retired from GM. He would tool around on his Caddy and light up the tires and smoke out the neighborhood as he'd burn rubber. Great old guy.

Wow I never realized how good the torque numbers were , 550lb ft that’s 100lb ft more than the 454 SS which had 450 gross, from only 800cc more displacement

I had a 1965 Lincoln with the 430 ci plant & a 462 ci plant in my 1966 Lincoln, it did put out great power, as did my several 440 ci Chrysler's I've owned. The only American brand I've never owned is a Cadillac which I've always wanted but for some reason never pull the trigger on one.

The new Cadillac engines sound like sewing machines JUNK

A wonderful profile on a great engine & the early 70's iconic Cadillac's!

My father had a 1975 Coupe de Ville with the fuel injection engine. The only real issues that I remember were some of the fuel injection sensors. It would get 10 miles per gallon in the city and about 16 to 17 on the highway. Not bad for pushing 3 tons.

I miss Pontiac muscle cars

The Ultimate Torque Monster.

I was in high school auto shop and also working as a pump jockey part time in 1973 when the Arab oil embargo hit. One of the teachers brought in her 1967 Caddy with the 472 and begged us to tune it up so it got better then the 7 MPG it was getting in city driving because she couldn't get enough gas to go to and from home everyday. She ended up donating the car to the school when she bought a new VW because VW wouldn't take the Caddy in trade. Gas had gone from 36 cents to around 75 almost overnight and that was when you could find it. Gas stations were closed on Sunday and most wer closing at 6pm.

$0.36 in 1970 is equivalent to $2.91 today. That's not cheap gas. Well maybe if you're a Cadillac owner. Love the videos. Keep up the great work!

Sometimes, "BIGGER" is "BETTER"!!!!!!!!!!!!Go USA!

Missed Ya my brother!!! That torque was Insane!!
