Gen III / A body...high 10's / low 11's...street strip car. Anyone?

You certainly dont need a hellcat motor. My 2011 challenger ran 11's at 4200 pounds with a stock 6.4. It had a 5 speed and 3.06 rear gears. 1000 pound lighter car should go 10's. You can put a cam in it and make 500 wheel horsepower and go well into the 10's
