FWIW, Wallace calc is showing a little over 650hp, nice job!!! Takes some doing to set the car up for it too! Would love to see some actual dyno numbers if available.
I think the guy with this car has full exhaust all the way back and the convertor was off. It was run down in Cincinnati this past summer.
ET’s and everything line up with the blue 71 Dart that averaged 9.95 while completing drag week.
Kinda makes me want to do a roller in mine so it would run 9’s, but this offseason I am concentrating on repeatability and making the driver better instead.
New battery, new rear drum brakes, perhaps air shifter, appropriate size fuel pump and a practice tree are in the works.
