HV oil pump vs Stock oil pan

Bewy said

That is why I did my testing AFTER the oil filter, which I stated in the post above.
The rockers in the 340 are not connected to full time oil pressure, they get a pulsating supply at idle from the cam journal holes lining up with each bank. So would expect lower pressure at the shafts.

So which is it? You said there was a 5 psi drop in the system and I said no, it’s much more than that. And it is. Damn dude, get it straight. Running that low oil pressure at idle starves the rockers and cam bearings. Most guys on here don’t build dead stock stuff. As the spring pressures go up, the loads on the rockers and cam bearings go up. You loose way more power with the cam sitting on the cam bearings and the rockers grabbing the shafts than you do running 30 psi hot idle pressure. Pressure is resistance to flow, so you also have a flow issue. I just watched a UTG video this morning because it was sent to me and he said the same low oil pressure nonsense.
