i'm planning a killer game of musical chairs. i'm removing the tbi 355 & built 700r4 from the big black blazer and putting it in the new 90 k5 i'm picking up thursday. i'm taking the 90's computer, tbi, and heads and putting them on the 305 in my 54 chevy truck. and the big black blazer is getting a 500 from a 74 caddy. my question is, does anybody make an adapter to put a np 241 behind a caddy trans? or a 350 or 700 trans behind a 500 caddy? it'll be a while before it gets done anyway, but i'm brainstorming.
