I'm preparing to do an L67 top end swap on my 03 Monte Carlo SS. I'm no mechanic but between me and my brother i'm pretty sure we could pull it off. My brother has an 01 Grand Prix GTP and we were basically gonna look off of his engine and put it together that way with a bit of some knowledge on the engine to help us out. I have done an engine top end rebuild on a 350 V8 engine before so its not like i dont know my way around an engine. Mainly what i'm looking for here would be some instructions (in pretty good detail) on how to go about switching over from one to the other!!! Any advice/comments will be very helpful!! Thanks in advance!
