I was going to do a 5.7 turbo, having been inspired by your 360. Since my Cuda is an original 440 car, and to simplify things, I'm sticking with the big block, so the 5.7 stuff I bought is available. 2003 5.7 long block, plus 2 6.1 cranks, and a truck timing cover. I thought the high mount alt. might help pipe routing, but who knows. Keep the updates coming, I love reading about that thing !
