At 28-2900 rpm at 70 miles per hour indicates a 3.08:1 final drive. The TA radials might be a little taller than the original GR-70s, but probably not. MPH per 1000 rpm with the 3.08 was 25.7. Listening to the engine indicates the M-20 wide ratio 4 sp, which came standard with the 3.08. The M-20 is VASTLY superior to the no-ratio M-21. An M-20 3.08 is the equivelant to an M-21 with 3.55 in the first 3 gears. Nice car.

The Vette needs re gel-coated and painted.
