When I started my project I was going with an LS engine it was one of the things I really wanted to try. I have other LS powered cars and they are just amazing. The LS engines just wind up so quickly and make so much power they are awsome little boogers. I just have a problem, once you own, operate or just drive a car with 500 cubic inches its just a whole different world. I am not sure how to describe it. I decided to build a BIG BLOCK, because cubic inches just make me happy! ( I must be making up for for some other shortcomings)
