I'm thinking about taking my truck to the track to see what it'd run. Now, here's the thing, I could CARE LESS about what my E.T. is, all I'm concerned about is my MPH. With a 3.73 posi would my MPH be different, than having my 4.10 pegleg. (We're assuming same tires, no drag radials, just plain Kumho 255/55 17's)
