Reply to "Oil Pressure??.. What say you??..."

I will respond in saying I agree with George "However, the best Ford recommendation is to blueprint the standard volume pump, setting the rotor clearances at 0.002" to 0.003", and run the high pressure spring as recommended by Ford."

WHY ? Because is you have a oil system with 1/4" oil passages and you put a guage to measure gpm at the end with all the leakage thru bearings clearances and lift bores ..at the end if you had 2 std pumps and one had a high pressure spring which one would read a greater gpm ? The higher pressure ...so in an engine with oil configeration issues where certain main bearings get oil first and others later ..which would be likely to provide an even flow of oil to the end mains ?

I hear the rest of the comments ..most issues are not even related to just the pump ... my experience with OIL ISSUES were mostly on a FE motor .. we restricted the rocker shafts, and opened up all the oil passages we could with long drill bits ... never spun a bearing @ 7200 rpm. Yes I agee there are other issues created ..there is always a trade off .. but not spun bearings and broken parts.

Take a peak at what our TUNER friends are doing. Lighter oil ! Higher pressures !
