Run a search. There is a post somehwere listing all the motors that will fit our Trucks (some harder than others mind you, and I would search and find it for you but I am in a hurry).

I am pretty sure that the 4.3 will bolt right up as long as you have the 2.8 now. However, not sure how hard it would be. <img src="/forums/images/graemlins/kewl.gif" alt="" />
