Has Anyone Put In A V8 Cadillac 472 In A 80s C20 ?

Anyone who puts a 472/500 Caddy in something does so either because they got if for next to nothing or they want to be different.

They've got torque like a locomotive, and people do make speed parts for them. I remember seeing a vendor that was all they did-could sell you the parts or build full race motors to any level. They're torquey-and strong. Turbo? Sure. Nitrous? You bet. As long as you don't spin them too fast they'll shrug off just about anything.

For most people, a big block is the better choice. But some folks like to get weird with it...

I shift mine at 6500 runs through the traps at 6600. It has hit 7000.

that’s enough rpm for my combo.
 
When you have a half a million or some chit ftlbs at any rpm, you don't have any reason to go to 8-10 k lol

Nice. That's pretty high for those motors. One of their Achilles' heels was a weak valvetrain in stock form-couldn't take a lot of revs. Not that they really needed to-torque peak occurred between 2-3k rpm depending on year.

in stock form, very true. They absolutely were not designed for higher rpms.

im running a solid roller lifter and roller rockers. Actually upgrading the rockers this winter to a new design from Harland sharpe.

You can make power from a Cadillac 500, but it's not cheap. The first thing you need to decide is how much power, then make choices after that.

If you want to spin it fast, the factory valvetrain needs to go. If you want to eliminate the factory valvetrain (rockers and lifters), then it's actually stupid easy to get 525/650 out of it and still have 9" of vacuum at 650rpm. More than that and you need to find "good" heads and have some fun with a die grinder. Even then, you're still limited.

I always ARP stud everything in them. It'll spin them like a smallblock then. The crazy thing is that they weigh what a cast iron smallblock weighs.

These days though you might as well build a direct-injected 6.2L and if you keep the VVT you can get the same power out of an even lighter package for the same money.

However, there is no replacement for displacement.
