And a hundred more are out there. One thing more you need to know is how much your converter slips. Rule of thumb is around 10%, but they vary.

Alright so i used the calculators and i had to estimate the mph because i haven't ran the car yet. I estimated around 115 or 120 for mph and with my tire height i'm getting around 6500-6600 rpm. Is that too high for the quarter? should i think about replacing the gear with a 3.73?

I have a 98 Pretty stock LS1/A4 with 100 shot, 4:10s and 26 DR Stock stall last year. Car went 12.4 at about 112 would hit 4th gear right at 1/4 mile mark. Car is also a DD car cruises 26ish at 70. Put a 3400 stall in it this winter. Love the 4:10s in mine. 3:73s would not be bad either I bet.
