Just checked it out on the analyzer. With stock tires your 80 mph rpm is 2190 with the 3.08, 2524, 3.55, 2652, 3.73 and 2916 with the 4.10.

With the stock motor it may slow you down to go higher than 3.73 but I would go 3.55 for a mild daily driven mostly stock car. How often will you notice the 0.1 - 0.3 in the quarter?? With more exhaust and intake mods the motor will make more power at higher rpms, and would respond to the 3.73 or 4.10 gears, remember those AOD guys have a deeper overdrive gear too.
