RE: gear and stall question
I would go with 4.10 gears and a t-lock. You are right about stall converters acting different for different motors but also weight affects them. Why did you get such a big cam for a street car? If you didn't get heads or do major head work on yours the cam will never produce like it should. Peronally I would have gone with one from 1500 - 5000 to help maintain low end power for the street.

Gearsets for the 7.5" include:
2.73
3.08
3.27
3.31 (stock 05-07)
3.45
3.73
4.10 (*?)
4.11 *
4.56 *
*The 4.11 & 4.56 gears need that "notched X pin" that everyone sees in the online catalogs.

I have heard that if you have a stick shift to go with 3:73, if you have an auto go with 4:10s, thats seems to be what most people say. If you do have an auto here are a couple of things that might help you lower your 1/4 mile time. You should shift your gears yourself, just don't red line it then shift, my buddy did that to mine and cost me 1500 bucks to get a reman. tranny and new torque converter. Also hold your brake in and push on the gas, but don't spin your tires, should give you a better jump off the line, atleast it does for me. By reading this you agree not to press chargers if my advice causes any damage to your vehicle, lol.
