post some pics of the crew when you get time. Mine will be getting a lq4 and an s475, I kicked around the Cummins idea and decided to do the ls instead.
stand by for pics of the brown bomber. And like you I just recently picked up a 5.3 and plan on getting a snail on it before it goes in and the frame gets a chop. Cummins are just too damn expensive. Ill take 5xxhp/5xxtq on a budget over black smoke and clatter.
