Surprised several years ago a buddy talked me into replacing my 3.91's with 3.23's. Ran 12.20's and 112 w/3.91's and 12.40's at 111 w/3.23's. Mileage went from 9 to 13 one the road, 65mph. Motor makes 511hp 580tq 500in...it doesn't care much for a deep gear. Torque motor.


The little old lady from Pasadena is back!
