GM’s CRAZIEST and BIGGEST V8 ENGINES ever made | You didn't know about!

[@CookeZachery]

I worked on plenty of Cadillac 472 and 500 V8s back in the day. Those engines were bulletproof if you kept up with the maintenance. I’ll never forget a customer who hit 200k miles on his Eldorado without a rebuild...

[@MuscleCarMasters68]

That's awesome The Cadillac 472 and 500 V8s are legends in their own right. Those engines were built for the long haul, and you're absolutely right proper maintenance was key to their longevity. The fact that your customer hit 200k miles without a rebuild shows just how tough those motors were. It's rare to find an engine that can go that far without major issues, especially when it’s pushing all that torque!

Sure, they were tough, but that torque monster wasn’t always practical. They guzzled gas like it was free, and let’s be real-most people didn’t maintain them like they should. I’ve seen plenty of these beasts junked before 100k miles because folks didn’t check oil regularly.😁😁😁

[@MuscleCarMasters68]

@@AdelynDodson You’re absolutely right! Those big-block Cadillacs, like the 472 and 500, were torque monsters that could really move. But yeah, fuel wasn’t exactly cheap, and without proper maintenance, these beasts didn’t last as long as they could’ve. It’s a real shame to see them junked before 100k miles due to lack of care.

I am really surprised they didn't use the Cadillac 472/500,in the GMC motor homes,not that there was anything wrong with the 455 Olds, it's just the Cad engines just would have done a better job lugging around the coach.

[@AdelynDodson]

@@patrickmcgoldrick8234 Honestly, I’ve gotta say I think the Olds 455 was the better choice for the GMC motorhomes. Sure, the Caddy 472/500 had more grunt, but those beasts drank fuel like a sailor on shore leave. The 455 wasn’t exactly frugal, but it had a balance of power and reliability when maintained properly. Plus, parts availability and simplicity made it easier to service.

Sure, it’s not going to blow the doors off at a drag strip, but that big Caddy V8 was built for long-haul comfort and unmatched durability. I’ve seen Eldorados with 200k miles still pulling strong without a rebuild.

[@AilaniMadden]

The Buick 455 might have that mid range grunt, but let’s be real Olds 455 had the durability edge, especially in high-performance builds. Buick's oiling system was its Achilles' heel, and without major mods, it just couldn’t keep up in sustained high RPMs. Sure, the LS6 454 had factory backing, but even without it, the Olds 455 W30 proved its muscle on the street and track.

Thanks for your comment The Buick Super Duty 455 Stage 1 is an absolute powerhouse, no doubt about it. With its massive torque and legendary performance, this engine was a game-changer for muscle car fans. The Stage 1 package offered a perfect balance of street and track-ready power, with enhancements to the intake, camshaft, and exhaust system that pushed it to new heights. It's a true icon of the American muscle era We love hearing your thoughts drop a comment, share your experiences, and don’t forget to subscribe for more Let’s keep the muscle car legacy alive Keep the comments coming, hope to see you next videos.

the Buick 455 Stage 1 is legendary for torque and all, but let’s not act like it’s untouchable. Sure, it pulled hard off the line, but compare it to a 426 Hemi or even a 454 LS6, and the numbers tell a different story. The Buick was built for cruising more than tearing up the strip, and it showed. Not to mention, Stage 1 cars didn’t have the same aggressive cams or high-rev potential as their Mopar or Chevy rivals.

There was a guy named Lilly from Erwin TN who always put 500cid Buick nailhead engines in stripped Novas they were fast he even removed the bumpers and had PVC in there place

[@KeithGreene-k1v]

a 500 cid Buick Nailhead in a Nova sounds wild, but I gotta say, it doesn’t sit right with me. Stripping bumpers and replacing them with PVC? That’s cutting weight, sure, but at what cost?

[@Samuel-l7y1d]

@KeithGreene-k1v it's crazy for sure I was a teenager at the time he was a crazy guy

[@MuscleCarMasters68]

@Samuel-l7y1d That's a wild story Lilly from Erwin, TN, sure had a unique approach to muscle car madness. A 500cid Buick Nailhead in a stripped-down Nova? That's the kind of thinking that made the muscle car era legendary. Removing bumpers and swapping them with PVC just shows how far some guys would go to shave weight and make their rides faster. Those kinds of cars were built to tear up the streets and leave an unforgettable impression, both for their insane speed and the wild mods. For all of us gearheads, these stories remind us of the crazy creativity and love for performance that define American muscle cars. We’ve got to keep that spirit alive, so let’s hear your wild car stories, too Comment below, share your experiences, and don’t forget to subscribe to American Muscle Cars to keep the legend going strong Let’s keep the passion for these iconic rides alive, folks

Oldsmobile 425

[@basilcarroll9729]

Legendary !

[@MuscleCarMasters68]

Thanks for your comment The Oldsmobile 425 V8 was a powerhouse, introduced in 1966 as part of the bigger and bolder push by GM for muscle cars. With a bore of 4.12 inches and a stroke of 3.975 inches, it delivered around 370 horsepower and was a favorite for its smooth torque and performance. This engine made waves in muscle cars like the 98 and Delta 88, providing thrilling acceleration and a unique exhaust note.

@ This engine was given to me that came out of the Delta 88 when my friend died. Before I could get my hands on it the heads were taken by a mutual friend to pair with a 455. He offered me the 455 heads but I turned it down cause because that combination only worked in his favor. Went on to a 396 in a camper special and. 68 Chevy with a 8.9 in. bed. Always had dreams of building something bigger and better but got a back injury that put an end to all that.

[@MuscleCarMasters68]

@@skidmark7845 Thanks for sharing that story! It's tough when dreams are put on hold, but it sounds like you've had some serious muscle car moments. The Oldsmobile 425 V8 really made its mark in the muscle car world, offering that perfect balance of power and torque that made cars like the Delta 88 and 98 such legends. It's crazy how a simple swap, like the 455 heads, could change the entire game, but it sounds like you knew what you were doing. We love hearing about these stories and celebrating engines that have shaped the muscle car legacy. Have a good day.

Only ford made 1100cid gas . Buick made 630 cid 4cylinder

[@MuscleCarMasters68]

hanks for your comment Ford was the only one to produce a 1100cid gas engine, which was part of their massive powerhouse projects. As for Buick, they did indeed develop a 630ci 4-cylinder engine, but it’s important to note that these were really special engineering feats for their time. Both engines represent the raw power and innovative spirit that American muscle cars are all about!

What happen to 427

[@MuscleCarMasters68]

Great question The 427 GM engine was a true powerhouse, and its legacy still echoes through the muscle car world today. The 427 big-block engine was first introduced by Chevrolet in the 1960s and was featured in iconic cars like the Corvette and the Camaro. It came in various versions, including the high-performance L88, which made a massive 430 horsepower from the factory. Unfortunately, due to evolving emissions standards and changing consumer preferences, GM moved away from the 427 in favor of more fuel-efficient options. But make no mistake, the 427 remains a symbol of raw American muscle. It's a real shame to see it go, but muscle car fans are keeping the flame alive! For all the true gearheads out there, let’s keep the spirit of the 427 engine roaring through our rides.
