I think it was a combination of things. Losing the cam sync made the timing fire where ever it wanted to, thus beating the rod bearings, none of them fit nice in the rods when I took it apart. And the fact that that on the third pass the new shifter locked between 2nd and 3rd gear sending it way high in the RPM, the high rev limit was turned off. (my fault) I don't blame the block in any way. The last thing is the oil pressure has been dropping about 10 psi above 6000 RPM, that's why we decided to change the pump. According to Titan oil pumps I was cavitating the pump at higher RPM.
