Re: trying to break into the thirteens.
Swapping from 3.07 to 3.73 is a world of difference. I swapped mine from a 3.42 to a 3.73 and picked up a little over half a second. How much time you pick up depends on your setup. What kind of rpm range your engine runs, your transmission, stall convertor and so on.
