I am at 3012 lbs, torqueflite, 4.56 gears and 33 tall slicks. Stall is 6200 and the motor was 550 cubes, fully ported 440-1, 3x intake and alky injected. Still sorting out suspension settings. Best 60 ft 1.24 best mph 154. I mention all this because with the right cam i believe you will need to shift at 7600 and recovery needs to be 6600 because your best average hp will be in that range. I shift my 550 at 7450 rpm, recorded on a data logger. Peak hp on the dyno was 926 hp at 7200 and was still climbing.
