RPM alone doesn't prove anything, but yes, I got 6400 RPM with the 2.176 : 1 drive ratio and 7300 RPM with the 2.85 : 1.   I beat several O - 360 RVs with both setups.

You said it, Tracy.  RPM is as useless as torque as a standalone figure.  I could get 10,000RPM out of my truck engine.  All I'd have to do is remove that shaft going to the rear axle. ('Course then I'd have to send my boys out to pick trunk engine parts out of the neighbors yard 8*)  It is ONLY when the two are combined that we get any meaningful information.
