What do you think it could run?

Back in the day....my 69 Charger, 383-2bbl engine with stock short block, original iron heads with bowls blended, 750 vac Holley, Eddie DP4B intake, old 284/484 MP cam, 4.10 gears, 27x9 5" slicks. 13.0's. Never made it to the 12's. But that was like your car pulling a 1000# trailer as it tipped the scales at 4260#'s plus me!! You'll easily be low 12's or into the 11's if it will hook.
