point of reference, that there's more to it than just gear ratio...all calculations assuming no converter slip.

at 70 mph, a 2.76 rear with a 26" tall tire is turning 2500 RPM

the same tire (26") with a 3.23 is turning 2900 RPM

the same gear (3.23) with a 28" tall tire is turning 2700, and with a 30.5" tall tire is turning 2500 RPM at 70, the same as a 2.76 with a short tire....
