i think the motor was built poorly. I have the rev limit set to 7500 with a built top and bottom end. It might of been over-reved and i just dont want to admit it.

what was modified in the valve train?

I say whoever did the build didn't shim the valves correctly..

Well there were 3 shims found in the oil pan. I really think they guy that built the motor screwed up but i cant really prove it. He installed the cam timing wrong and did a few other things.I had:JWt C1 cams, Ferrea Dual Valve Spring, Rocker arm stoppers, and some other stuff i cant think of right now.
