cortcomp - You saying I'd be better off (mpg wise) with the 3.73's or 4.11's? As far as the stoplight fun, with a 2.97 1st gear and 3.73's giving a 11.07 1st gear ratio and 4.11's giving a 12.20 ratio and 450 lb/ft of torque ... 1st gear might be re-labeled "tire melt" ... LoL
For comparision sake, a Muncie 4 speed and maybe a TH 350 has a 1st gear ratio of 2.52 and even with a 4.10 rear gear, that equals a 10.33 final ratio.
