Stock 2.73 to ??
With a stockish engine, there would be very little performance gain stepping up from 3.42 to 3.73.
I have a 3rd Gen F-body with 3.73's, stock engine, and I would prefer 3.42's. It's always operating too far above the engine's torque peak with the 3.73's.

373's at 75 mph was 3000 rpm
342's at 75 mph are 2500 rpm
My 60" time's are .2 th's better with the 342's but the new relocation bracket's are probably the reason for this but it went from 2.0 60's to 1.8 with stock stall and tranny.I am overly pleased with the ratio
