To select rear gear, you really need to have good estimates on trap speed, maximum engine speed and converter slippage. After this, it is just a math exercise.
If you have 1000 rwhp you will have impressive trap speeds - what are your engine rpm limitations?

3.70 gears are what we had in my Camaro, shown here. http://www.exoticperformanceplus.com...Car.php?car=12 We had a turbo 400 in it, then swapped it out for a powerglide. Bob
