7000rpm / 1:1 / 4.22 = 1659 rpm a wheels
65" * 1659 * 60 min/hr / 12"/ft = 539,099 ft/hr
539,099 /  5280= 101.102 MPH

Thanks
Duncan

Hi, I was just wondering if someone could help me out with the speed I was
going... I have a stock 4spd tranny, 4.55 rear end, 7000rpm, and tires are
65" in circumference.

Thank you guys! I just installed a new rear axle because it was broken, and
I switched diffs to a 4.22 and when i removed the 4.55 a handfull of teeth
came out with it.
