Really??? An LS4 swap in a 97-03 body?? For real? You're really doing this? Please, keep us posted about this. I've been wanting someone to do this on this body. LS4 has plently of potential, other than the turbo guys no one has had the balls to do much to one yet.
BTW, I was hoping to meet ya ay Branson this year. Hope you possibly make, GP or not...
