OK- - - -I miscalculated the ratio change. The ratio should be around 4.50:1 (probably the 4.56 gearset). Try turning the driveshaft 4 1/2 turns with one wheel jacked up. You should get 2 turns of the rear wheel, since the spider gears are doubling the wheel speed. That's one reason not to get heavy on the throttle if you ever get one wheel spinning in snow or mud- - - -the wheel that's spinning is doing twice the speed the speedometer is indicating.
