Hey guys. This question is for all you guys who have done MAJOR renovations to your 4.0s. Im talkin bored, stroked, cam swaps, all the internal stuff. My question is how hard is it to come by 4.0 performance parts? It doesnt seem like a very "potential" engine but I may be wrong. Is it possible to get 300 hp out of these engines? If so how much does it cost? And how much did your mpg drop? What are the upgrades you can do to these engines (cams, stroker, heads, headers, intake, etc)? Thanks guys!
