First time out with tranzbrake ??
I have a 71 Demon small block stroked (426 cubic inch) with a 904 tranny ,transbrake and a 8 inch torque converter. I launch at 3600 rpm but I would start at 3000 first just to see how your car reacts. If you go up higher in the RPM the front end will come up quicker and possibly spin the rear tires. I have been using a transbrake for 7 years. I have both foot braked and trans braked it and it has the same 60 ft 1.38. i like the transbrake...good luck.
