472 Caddy in a 67-72?

Just curious. Has anyone here ever shoehorned a 472 Caddy engine into a 67-72 Chevy? I know there is room, just mainly wondering if anyone has done it and if there were any major obstacles that caused problems.

Re: 472 Caddy in a 67-72?

I dont know if a 472 is the same as a 500 but there have been lots of threads on the subject. Maybe do a search on Caddy or Cadillac?

500 is just a bigger 472.

Re: 472 Caddy in a 67-72?

472 is a 500, I think the only difference is the crank. If someone says 500 block, they can mean a 472 or a 500.

Re: 472 Caddy in a 67-72?

yes, the crank is the main thing between a 500 and a 472.
A quick rundown of how I did it...
Need a BOP trans to bolt up, possible drive shaft mods depending on tranny chosen
Fuel line run onto other side of engine.
Dimple firewall on drivers side
flatten the flair on passenger side frame rail up towards the front.
use 73 - 87 truck engine stands, drill large hole in center, and lop off front lower corner (upon mock up you'll see where it's needed and why)
Caddy rear wheel drive manifolds, rear sump pan, I used eldorodo motor mounts, a 425 oil pump is smaller and clears the front crossmember with no trimming, a 69 472 fuel pump is 3/8 in and out with no return line... I think that's about it, plus some moving of wires around under the hood to relocate the alt onto the passenger side.

You'll want a 3.07 gear if it is a street driven truck.
4 row rad is a must
get strong U joints
bald rear tires are a common problem too.
MPG generally goes up considerably once you stop playing with the torque and just driving it.

Re: 472 Caddy in a 67-72?

there's little details that I have long since forgotten, but that is in all reality the main things to the swap.

Re: 472 Caddy in a 67-72?

I'll be the first to say that my wife has told me more than once to get off the damn forum and get something done. I just tell her I'm providing good, technical information.

Re: 472 Caddy in a 67-72?

I have a buddy with a 472 he's about to throw on Ebay. His grandfather ran a funeral home and this engine was in one of the hurses. Car was a local driver, not many miles..

Been there done that check my build for all the info and not to step on LongHorns toes but I didn't "tune" the fire wall...it's 100% bolt in if you use the right parts and I did it by myself in 3 days including cleaning and painting everythin which took a day...If you have any questions I'll do my best to help out

Re: 472 Caddy in a 67-72?

I didn't have to, but I wanted an inch or more between the drivers side valve cover and the firewall.
There's a million ways to do it.
