Hi, I have this 86 Bonnevillethat had a3.8 engine and I believe a TH200 trans, I want to drop asmall blockChevy into it along with a 700R4, what kind of trouble can I expect? The engine & transthat I have is out of a Chevy truck & the 700R4 electronics have been bypassed.

Not much going on at this forum.

Gonna use a different engine instead of Pontiac, kinda used hearing this but you need tons of mod to make the engine fit, like brackets and other engine components.
