I'm not sure what cam is in the motor. All I know is the fellow I bought the car from said that it was a small cam so it would hammer the springs as bad (????). The motor just seems to nose over on the top end great to 1/8 mile (1.12- 60' 4.98- 660') but flattens out on the 2nd half. I figured it was the cam but maybe its the head/ intake combo?
