G52b was only offered 79-82 in the trucks. It'd be a narrowblock motor most likely also.

The g52b uses different intake manis and some different things. The old Colt performance mag said to swap the g52b head on the g54b and bump your compression up to bout 11:1

Ive got a dual sidedraft intake mani for a g52b. I've been collecting g52b's just b/c there hard to find parts for.
