He's right. Not only have I seen it done....I just finished doing it. Very easy, IMO.
I didn't cover the small deatails in my thread, but I'll cover some here for you:
ALL Gen 1 (1955-1997) Small block Chevy engines share the same architecture. Meaning, they all look the same, parts are interchangable (for the most part), and they all have the same dimensions and bolt to the same bell housing. All SBC blocks from 265 CID up to 400 CID.\
It really doesn't matter what application you pull an engine from. Mine was from a '77 Caprice. But it could have come from anything. Get the ENTIRE engine assy; Water pump, pulleys, intake, carb (or EFI), harness, manifolds, alternator, PS pump, distributor...everything. Get it LOADED. Then you just drop the entire package in, as is, and hook stuff up.
There was a switch to a one piece rear main seal in ~'88. From that time on, the flywheels are different; they have a smaller bolt pattern, and a counterweight cast in.
Email me or PM me if you have more questions.
