Ben,

Having gone thru the same thing a couple of years ago, I know exactly how you feel ... I would take apart the oil pump & check it closely ? I asume the cam bearings were new ? I agree with Rich, you need to look at oil flow to cam bearings ? You also could have a bad cam bearing ? Look at everything you can while you have it apart ? How was the oil pressure on the dyno ?
Could have been a single piece of dirt /metal on one bearing ? I would check the cam ( several times ) for straightness & ground in metal ? Better to be Safe than Sorry ... Good Luck & keep us updated ........... Dave,
