Just go with stock pullies and a power pipe..... If you want more power go with a 2.95 and stock crank for more.. Get a tune any which way!!!!!

You will see 12-13 psi with the 3.33 and 8 inch crank and powerpipe. Just make sure you get the 93 Cobra water pump pulley with the 8 inch crank pulley. If you dont the belt will be touching the WP pulley. Easier to do a powerpipe, 2.95 pulley and stock 6.87 crank.
