Putting together a 2012 5.7 to run in my 70 Duster to run in street class , you can run as quick as 11.5 on dot tires. Since the motor is rated at 390 hp in stock trim I would not think it hard to achieve in a 3200 lbs car with a 4spd and 3.90 gears. Plus I think the fuel injection would make it more consistent in all weather conditions.
