6Pakattack has the right :angry7: MP cam. The failure rate for this cam is the highest we have seen. However the data suggests that it was due to racing and high RPMs. We dont really know. I believe just about any cam manufacturer has had a issue with the cam to oil pump drive gear failing. My personal belief is it is the oil pump drive gear that fails Not the cam. This is why Doug Dutra and I have been getting the gears Heat Treated. We both have them for sale and as far as I know we have not had a failure (even under racing conditions)
