I'd go with a 2600-3200rpm stall for a street driven LS1 with 3.73's. Generally speaking, with better gears in the rear you don't need as much stall. This is because you won't spend much time below the stall speed and even when you are you'll have mutliplied the engine torque PLENTY to get off the line hard. For this reason alone I never recommend gears with a radical converter. You're gains will be minimal. Infact, you could even loose performance with too high of a converter if it's still a large diameter beast! Most of the gains are actually had by not the increase of stall speed but instead by the lower inertia and higher torque multiplication during slip. So 10" and smaller converters don't necessarily need to be ordered with a high stall, especially on a near stock motor. Just my 2 cents about that.
