um get like a 416 bore... maby 426 kit... get a full exhaust the sparks full system is the best of the best.... um K&N air filtered. jet kit and i wouldnt worry about a rev box.... possible a Stage 1 Cam would be benifical to ya... and idk if you do this after you bore it but port and polish. and possible stick a clutch kit in it after you bore it,..... hope this helps!:cool:

drop a tooth in your front sprocket for acceleration and gain a tooth for speed
