My previous 4.210 stroke 462 combination made peak power on the dyno at 5800 rpm (580 hp) and we used a 6200 rpm chip in the shift light.
I can assume it was closer to 6000 rpm (?) There is reacting to the shift light and the physical time to make the shift.
I have a time slip for a 1.6 60-ft and 10.88 at 124.28 mph.

Again for conversation only, but entering the numbers into the calculator I posted works out close:

28 inch tire (88" circ.)
6000 rpm
3.73 gears in use (TH400 trans)
6.7 Torque Converter Slip (%)
124.28 mph


That amount of converter slippage the calculator indicates is not out of the question for the converter at the time.
I sent my dyno sheet and car specs to Marv Ripes at A-1 and he built a custom 8-inch unit for us. It had about a 4200 rpm stall.
