I was thinking of a 3.8 engine as well. But I don't know. My ecotec is crap. I don't know what's wrong with it. And if i'm going to get a new engine, I might as well see if I have enough funds for a bigger swap (ls4, ls1, maybe ls2). I have quite a few bucks put away, enough for a swap belive it or not, but I don't know if I want to do a silly swap or actually buy a NEW camaro with a warranty lol
