The lowest RPM's Ive seen someone run at high speeds was with an aftermarket 3.44 R & P and an .82 4th gear. He was at 3200 RPMs at about 85.

A 3.88 R & P tranny with stock .89 4th gear and 25 3/4" tall rear tire will do 55 mph at 2500 rpm.

That same 3.88 tranny with stock .89 4th gear and 25 3/4" tires will do 100 mph at 4600 rpm's.
