How exactly do you pin it? I am running about 6psi on a 5.3 with a whipple.

It&#39;s a tool to drill a hole at the intersection of the crank snout and balancer pulley. You drill and ream a hole there and then drive a round pin in there to keep the balancer from ever spinning on the shaft. If you don&#39;t tighten the pulley bolt enough you can count on eventually spinning the pulley on the shaft if you don&#39;t pin it.
