So, I'm going to have to go through this whole thread to see who guessed the piston slap first so we can determine the winner. I will send the winner a Pontiac sign like I said I would. Hell, I'll even throw in some local Virginia beer. Hopefully we can all agree on the winner! Hahahaha!

I do have a question though. There seems to be some confusion if the bearing spun or not when it failed on the dyno. After reading the recent post, I do remember that it was discussed about the spun bearing. Has anyone heard of a piston skirt collapsing when a bearing is spun? Is that normal? What happens when a bearing is spun that could or would cause the piston to hit the head. Is that even possible? Considering that the knocking noise has been the same since when I first received the motor and stopped when that one piston was replaced, I would just like to get a better understanding of what happens when you have a spun bearing.
