the 4.10s are stellar for a hard rip off the line, but if you do a lot of highway travel then you might want to get something a bit less steep. the pulleys are a good choice, and the header, pipe, exhaust is always a good gain of HP, and a good sound. I agree with the shifter as well, and I'd also look into getting an aluminum flywheel, faster accelleration due to less mass to spin up. grats on the car. I'm picking up mine early this week
