The reason I was mainly considering a chev was for to free up some room as I was told they are a narrower V I am not sure by how much, I am also looking at putting bolt on EFI on which ever motor I go for, a 308 is definitely in the picture if I am not going to gain much in way of room, the other consideration was that resale wise a Chev maybe more sought after. Horse power wise would it be cheaper to buy a chev or have a 308 stroker and what is the best auto to put behind it Turbo 350, 400 or 700.
