8 INCH CONVERTER 4500 STALL

I can shift mine at 6200/launch 3800 and still run 10.0's.It works best at 7k on the shift and 4800 on the launch.The 388 I'm running is making good torque so shifting higher doens't net a more than a tenth 1/8. I pick up only .05 to .07 on the E.T shifting from 6200 vs 7k in the 1/8...I do run an 8 inch verter that breaks @ 5600.The cam I'm running is a Crower solid

longivity and the fact that I dont have to dress like john force for every pass make shifting lower a better option. :D
