Diff swap and changing gears
For comparisons sake, all in, I was 800 dollars for the 3.55 swap in my Mustang - paying someone to set it. That was pretty much a complete overhaul. I have a set of 3.73's and a trac-lok diff waiting to go in the old truck whenever I get the gumption. There are TONS of guys around here in the Mustang club, etc. that will set up a R&P for 300 bucks.
65 ~ 3000rpm or 2100 with OD
75 ~ 3600rmp or 2400 with OD
4.88 would be even higher ;-)
I would run:
33" --> 4.10
35" --> 4.56
37" --> 4.88
Sweet ****.... that is outrageous. Guess I should feel pretty lucky I know 2 guys that do this all the time. I really want to learn how to set one up.
