I built a 446 years ago with bowl ported Ede heads, 13:1, MP 620 cam, M1 with a 1050/4500 on it.
Made about 625hp on the dyno.

Went in a 3150lb race weight 71 Cuda back half car...... went 9.80’s.

Works out pretty close:

That dyno has to be modest. I now my car is heavier and the converter is killing my short times and the gearing is about 1,000RPM off but 600hp, 3450 with me in it, 10.98@124. HArd to believe there is a almost a second more in the car.
