The third cam, he used another brand, same procedure, and no failure. That was in the same engine the other 2 cams were installed. That was his final test to see if it was the cam, or an engine problem. So the same engine was used. It is still racing the track.

ps, Bill, I'm not advertising this. Just showing that the guy that told me has lots of experience in this field. I took address and phone number off his card.
In our IMCA mod. engines we had a couple cam problems and after checking into a few area's we found brand new lifters from two different cam companies that had a small dish in the lifter face rather than a crown.
