Piston Failure

Detonation can wipe out a Ring land in a jiffy. Just spit balling and not seeing the car don't be surprised if that's the problem. As for beating on the car at the track and having a ring issue, it could happen but that if the rings are properly gapped then that is not something I would put into the equation right now....

Pull it down and you will find out.

I'm definitely suspecting ring problems, I put it together myself. First bottom end I built, right out of highschool. I don't remember the clearances, but I thought I had given them a little more than what was called for. It's been through a lot and lasted this long, but this was the first big summer drive with this top end combination.
