High pressure oil pump?
It there any advantage to installing a high pressure vs high volume oil pump? My engine builder said high volume could starve engine of oil with stock 5 quart oil pan?
Does anyone produce a high pressure pump?
Thanks,
Chad

On Oldsmobiles, the thing that can possible starve the pan is if oil released by the lifters holds up under the valve covers. Oil released in other locations will drain immediately to the pan.
The high-volume pump has the same pressure relief valve setting as the standard pump. There's no extra pressure to force release of extra oil. If the system pressure tries to fall it will maintain the standard pressure and standard release in each location. For example, at idle, where the pressure is generally lowest, the high-volume pump would maintain pressure better. But the volume of oil released will not exceed a standard release rate. At higher engine revs, the pressure relief valve opens to dump the extra oil directly back to the pan--no extra pressure would build.
A high-pressure pump will cause extra oil to be released everywhere, including under the valve covers, which could then starve the pan.
Trust your logic.

Correct. For those who still want to believe the internet crap, block off the drainbacks in the heads and pour 2qts of oil in each valve cover. Then look to see what that actually looks like. Let us know your findings.

Out of curiosity....what RPM is your motor turning at 65 MPH with .5 overdrive?
I saw the lowest the Tremec TKX is .68 which would mean 2259 RPM with 3.91s and 25.7" tires
