Back in the early 70's in modified eliminator I had a roller cam that came from Jenkins. On the second pass I return to the pits, push in the clutch pedal and the motor would shut off. Pulled the motor and the cam was locked in the bearings. Checked the cam and it was straight. New bearing and back out the next weekend. After the 2nd pass the same thing again. Sent the cam back to general kinetics and they said there was nothing wrong. They made the statment that Jenkins does some strange things. Tried to solve the issue two more time with the same result. I finally gave up. I kept trying because that first pass each time my MPH was 2.5 more then usual. Something had to be done to the ramps on the cam that caused it to hammer the cam bearings and sieze the cam.
