For the MT, the 3.27 was optional


13" wheels with about 24" rolling diameter on tires.

I know that Dave said 1000 rpm, but I don't really think he really meant it. 
Reducing the rpm that much seems excessive and would be very hard to achieve.

I guess anything is possible, but with the bearing wear uniformly around the 
whole bearing, that hypothsis seems doubtful. In this instance, ring or cyl 
side load wear would seem more likely.
