Go with a thunder racing 220 or something in the same area from TSP. I got a step down from the 220 which is the old man cam and i regret not going at least a little bigger every day. Like stated earlier get the kit. You will need it. LT headers are a good buy as well as efans. Get a tune more then anything if you dont have one. Nealson is a good buy because if you plan on doin alot more upgrades he does retunes for free i believe. I advise going ahead and picking up billet servos and a shift kit. Because a good cam and everything thats been stated will QUICKLY end the life of a tranny. Thats why mine is slipping and in need of a full rebuild because i cut corners and didnt install mine when virgil and tyler did the motor.
