Wrong section but I can give you an answer... 1974 RWD Caddys like yours had the 472, which is a de-stroked version of the 500.

Check the bottom of these pages for some VIN info.

Thats one hell of a project your taking on. That car has paid its dues and then some. Wish you luck.

man, if you're married you've got one hell of an understanding spouse! I'd never hear the end of it if I started a project like that. I remember when she first moved into my place, it was suggested that I remove the Triumph 500CC motorcycle engine from my kitchen table (where I'd been rebuilding it) - and it was a very strong "suggestion"!
Best of luck with the buick - out of curiousity - was '53 one of the years where the speedo was a horizontal red gimick that went across the dash rather than the "sweeper" hand like most speedo's are? Maybe that was '55/56 - can't recall.
