[CUTLASSJESSE]

i bought a 82 olds cutlass a few months back that someone had done a 3.8 to olds 350 swap this car never had the option on a olds 350 so i was wondering if anyone knew where i could get the numbers off of the heads and block to have some idea of what i have thanks in advance, Jesse

You have a pretty good block to start off with, but the heads are not the best. I believe they are the start of the smog engines with low compression and crappy flow. They are not the worst heads, but it would be best to start off with some #5,6, or 7 heads.

Edit: I believe it is a 76 engine.

Actually, it could be 1973-1976. The second character of the VIN Derivative will tell for sure.

Don't believe everything you read at 442.com. That casting number was used from 1968 to 1976.
