Oil Pressure Drop Help....

What I wanna know is, what's the justification for an HV oil pump if he has an eight quart pan with a stock volume pump? He's certainly not pumping the pan dry.....not that he would with an HV pump either. If he's dropping to zero at any time whatsoever, he's got a problem somewhere. No baffles in the pan even with eight quarts could still uncover the oil pickup on braking or acceleration. Also, I saw no one ask which pickup he has. Is it a stock pickup with an eight quart pan? If so, there's your trouble right there. A deep pan MUST run a matching longer oil pickup tube that makes contact with the bottom of the pan, just like the factory did it, otherwise, it's entirely possible enough oil is being pumped out of the pan to uncover the stock pickup, even with a stock pump. It's an oil pump. Not an air pump.
