    Engine if tuned right should make 325ish on a good day

    ET is all hook and converter. Should go mid 12's pretty easy as long as it hook and tuned well.

      Weigh the car and calculate HP based on MPH

        Gears will help, but i bet it wont run mid 12’s. Maybe real low 13’s. Maybe. My guess would be 13.30’s or 40’s
