27 inches. Let me change my statement a tad.

I said 2200 rpm at 75. Won't compute. With 27 inch tires, 3.73 gears and the .7 OD, it will be more like 2400 rpm at 75 mph. With a 28 inch tire you would be around 2200 rpm at 70.

Then take into consideration of the lockup. This will lower the rpm around 200 rpm or so. This is where I come up with 2200 rpm at 75.
