Thread: Caddy Engines??.

Shoot 1gary; The 70, 501 caddy motor puts out 550 foot pounds of torque @ 2800 and 400HP stock. So it would not be hard to get 600 or more foot pounds of torque out of it.
Plus them old caddy blocks have alot of nickel in the blocks and they last for ever.

Thanks for the info.

Guys please keep the input coming................

my 16 year old recently purchased a 500 caddy machined block. he got it for $75.00. he then brought the matching heads for $125.00. he wants to do a mild build and drop it into my monte. he has gotten a job at subway to pay for the build but i am thinking that the monte will be setting idle for a very long time before he can get all the money together. right now he and i have purchased a 88 z28 and are putting my 350/350 in it out of the monte.

As Tech indicated, building a Cadillac 500 is gonna cost some money even if you go stock. Just for purposes of comparison, I bought a master engine rebuild kit from Northern Auto Parts. It cost me just under $860. The cost of a similar kit for a 350? Around $190 and the Chevy came with an oil pump which the Cad didn't.

jayp suggested Doc Frohmader's book "Big Inch Cadillac" and I definitely agree with him. It's good stuff.

There's some good reading at:

I hope that link works.

The engines are out there and they can be had very reasonably. In fact, I was given a '76 Sedan De Ville free. The people wanted the piece of ah ... wreckage off of their property. You may get the idea that it wasn't exactly a cream puff but I got the engine and a TH400 transmission just for hauling it off, then the recycle place gave me $90 for what was left.

That said, that was the ONLY thing about the project that wasn't expensive.

I have it in my head that big block Chev headers can be modified for use on the Cadillac heads by using new flanges and reshaping the Chevy tubes to match the Cadillac ports. Maybe that came from Frohmader's book. I'm not sure.

Good luck

Well, it looks like that link didn't take us anywhere.

Tell you what, if you have a fax machine at your disposal shoot me a private message with the number and I'll send you a copy of the article when I get home.
