If you subtracted 100hp for not having the “heavy hitter” blessing, then took another 10% off for installing the motor in the car, then knocked 2.5 tenths off for track elevation, and assumed the race weight was 3600lbs.......the ET’s achieved so far by the OP(12.30’s) are still over 1 second off what one would expect to see out of that basic combo.
That would be about a 11.25@117........ which shows 445hp@3600lbs.
