I know this has been re-hashed several times,but i would like to know how gear changes have changed 60ft times and mpg's.This car is driven alot by my wife,so i don't want it to be crappy to drive daily and gas mileage to reallly suffer.We are trapping 1.90 60's stock,with a best of 1.89.I have some 3.55's on the shelf,but i wonder if 3.73's would be better?
Thanks in advance.
