... You say you used a HV oil pump but I assume still using the standard capacity pan? I have some understanding that this is not wise - often the pump will suck out too much oil that sometimes can't be drained back in time...
This is not true. I ran a High Volume, High Pressure oil pump with a stock pan and pick up for years and over 100,000 miles in a HP 273 4 speed Barracuda that was never shifted below 3,000 rpm. Never had a problem. Of course more oil, a windage tray, and baffles would not hurt anything.
