Thanks Dave,

The M20 (2.56 first gear) that was in the back seat of the car when I got it is all rebuilt. This trans may be used for street, TBD.

The M22 (2.20 first gear) that was in the car when I got it is rebuild. This trans will probably sit on the bench.

The M22Z (3) that Nick just finished is a new gear set with an extra wide ratio. 2.98 first, 2.04 second, 1.47 third, 1 to 1 fourth. This trans is optimized for a reasonable set of highway gears like my 3.42's. This trans will most likely be used for PSMCDR and street duty.

PSMCDR only allows one size up of tires so G70-14 is the largest for me. I will most likely use F70-14's but TBD.

Rear gears are up in the air until the engine is run on the dyno, the overall power curve will be used along with all the factors you mentioned to select the rear end ratio.
