I had posted previously about jamming the oil pump shaft into the distributor shaft, and then pulling the pump shaft out with the distributor, losing the retaining clip in the process. The rebuilder says the retainer is too big to do harm and will eventually find its way to the drain plug. This averts pulling the pan and oil pump, but he wants to be the one to reinstall the shaft and distributor, to avoid dropping the shaft into the pan. So I'm hoping to fire up the stroker rebuild this week!
To those who suggested losing the mallet, I have taken your advice.
