Im going to go with a ported blower, 4lbs lower, 3.2 alt. pulley, and I don't know if I should go with a 3.1 upper or 2.93 upper, My tuner said that I should go with the 3.1 because the 2.93 will over spin my eaton and that there will be like a 5 HP difference between the 3.1 and the 2.93!!!
What do you guys think:shrug:
