Powerglide and rear gear?
With a three speed trans and a 14x31 rear tire we run a 456 rear gear running an eighth mile. I am changing to a powerglide with 176 low gear will i need to change the rear gear? If so what gear do i need? I have good parts in the engine rpm's up to 7500 don't bother me.I know the converter will make a lot of difference but just looking for some advice. Thanks
