ratio 3.55/4.10 = 115%
from 60>120+ your engine is working just as much as it used to with 3.55s when doing 60*1.15>120*1.15 = 70>140.

Just like any other mod it's going to take you a bit to get use to (especially gears). I had a buddy that ran a 08 GT full bolt ons and ran a consistent low 13's. He put a supercharger on it and 1st time at the track he ran a 13.6. Once you get use to the new gears and get the shifting down correct you'll be pulling alot harder than with the 3.55's....

Yes....4.10's will get you in your power band quicker in a short quarter mile race. Many cars do 4.30, 4.45 and 4.88 but if you were doing a mile race 3.31 would be better suited for that.
