I recently got a new engine and was wondering what it came off of. the engine is an olds 350 with number 3955582. does anyone know what year or model car this came out of?

try www.mortec.com

Hey thanks, Thats a great site, and i bookmarked it so i can find it again later, but the engine i'm looking for is an oldsmobile engine, not a chevy engine, so it isn't listed. Does anyone know what engine this is or a place like the above website except for oldsmobile engines?
thanks alot

does anyone at least know of a good BOP (buick pontiac olds) site that i might be able to find someone to ask? Thanks to anyone who can help me out.

Are you sure the 2 is suppose to be there at the end? There is an Oldsmobile 350 with a casting number 395558. Engine was used in 68-70. Or maybe the 2 references the second run of the block cause they also used them in 73-74.

Do you know if it has the stock heads? Look for casting number of 397742 ('68-'69), 403859 ('70), 411929 (73-74). The 397742 heads seem to be favored over the others.
