The problem with BOTH pumps is that the input shaft wears PREMATURELY AND WEARS the PUMP bore that the input shaft spins in. Air is sucked at the worn clearence that occurs between the input shaft and the pump as well as at the pressure relief valve port if it is not plugged. However, based on my experiments the amount of air sucked at the PR valve port is minimal.

This may be true, but the REAL PROBLEM is that the oil system is one big LEAK and the gear design in the Packard V-8 oil pump is completely inadequate in keeping up with the leaks as the engine gets older and wears, particularly the lifter bores. There is just no substitute for more pumping volume. The Olds HV oil pump outputs 20% more than the standard Olds pump which probably outputs more than the Packard pump.
