The flywheel needs to be in place to balance a 351w. It has a big weight hanging out at the outer edge which is necessary since it's an externally balanced engine, same goes for the dampner. The pressure plate is supposed to be neutral balance, so that it can be replaced without tearing the motor apart to redo the balance job. We always balanced the rotating assembly, then bolted on the pressure plate and corrected it's "neutral" balance. They didn't all need correction, but at 7500rpm, a little shake turns into a big shake.
