Oil loss is a possability, but it only ran less than a minute after the oil pressure zeroed out.
As long as pistons aren't scored or cylinder bore isn't too big/scored I'll be OK. This machinist specifically mentioned piston to bore clearance and honing stone grit # as the cause of the abnormal cyl wear.
Machinist says the shaft diameter plays a factor in dist operation. Since the HEI has a smaller dist shaft than the stock .490", it allows the dist shaft to wobble in the oil pump hole. He also said the HEI housing is slightly too small for the block hole, adding to wobble. He said the hardened thrust washer is needed as extra insurance against hardened gear/soft pump casting interferance.
More news as events warrant.
