So using the 1.77 gear ratio, you're still looking for a 6.9 to 7.5 depending on the track for a monster stock correct? Say I run a 120/35 with the 2.125, that gives me a 7.29, to get the same ratio for the 1.77 I would have to run a 120/29 roughly. Changing to the smaller pinion results in the faster acceleration if I am correct on my theory.
