Opinion from some of you long time Mopar racers

Looking at the moroso P/S calculator...... even if the motor made a pretty conservative power number(for that combo......550hp), and it was a typical 90% car....... it should still be going right about 130mph at NED in fall air.

Even 500hp and a 90% car shows close to 127mph.

Either the motor is way off the mark, or there are some problems with the car.
