Oil system myths

I modded my engine to pizz oil all over the place, and depend on the HV pump to still be able to keep up everywhere else. So far so good at over 100,000 miles.
People laugh at me when we talk about it but people also laugh at my flat Earth theory, so pizzonem.

I had a boss once that built a 340 for a customer, and the oil pressure went off the gauge. he spent hours working that pump over, to no good effect. He didn't want to hear anything I had to say. After about the third time the pan came off, he installed a stock pump, and the pressure was still thru the roof. I shut the heck up, cuz he was the boss, and like said, he was sure I would never know the answer.
So the days turned into weeks, and the customer's E-body languished in the corner.
I quit that job over other issues, and when I left, it was still gathering dust.
I had nothing to do with the designing or the assembly of that engine, so I wonder if, or how, he ever solved the problem.
