What gears for a c-4?

Don't go to high on the stall. At RPM's under the stall, the convertor is slipping some to multiply torque. If you have the stall over the RPM that you cruise at, then the convertor is slipping almost all the time. That creates alot of heat due to inefficiency and will make mileage worse as well as wear out the trans quicker due to high heat. I think around 2500 or so is a good stall speed for a moderately modded street driver. Actually, even after the converor has "coupled" at the stall speed, an auto tranny still slips some anyway (5-10% probably.
