this cam grind is used by top team in off road Trophy truck racing and in Late model circle track .
It produces strong power even at lower RPM, 3000 up. It comes with Description files and specks and average analysis of variance of lobe centers and over lap.
Specks on springs pressure requirements and cam timing.
I also have Jesel rockers set ups for the aluminum heads and Manton push rods of different lengths. Roller lifters and many sets of used and new valve springs. The used valve springs only have one race on them and are like new.
Message me if interested and I will list them.
