I am not sure how to start this thread, but my motor was running perfect earlier today. Then, my machinist buddy came over and disconnected the pcv and vacuum advance. Advanced the timing way up. Motor started running real rough and he said to drive it anyways. Then, it started running real bad. Loss of power across the board. Got the car home. All pushrods bent. Two broken valve springs on the #2 cylinder. I am/was running 1.6 roller rockers. Comp Cams solid roller cam and lifters .570 lift. I DID NOT over rev the motor ever. Why did everything just bend and break suddenly. I promise the motor was not wrapped up at all.
