332-428 Ford Standard Volume Police Oil Pump.

This SBC standard volume pressure balanced oil pump has been modified to provide a smooth continuous flow of oil through the full RPM range. By reworking the pump housing and providing feeder grooves, we bleed some of the high pressure back into the gears providing smoother operation and more constant pressure. This allows for the high RPM operation on a race engine and limits oil pump cavitation. Since it is designed for smooth operation at high RPM’s, the idling oil pressure can be up to 10 lbs lower than that of a standard oil pump.

332-428 Ford High Volume Oil Pump +25% volume.

*High volume performance upgrade for M-155HV *25% increase in volume over standard *Uses ¾” Press in Pickup Screen *Housing and cover are CNC machined and phosphate coated *Includes lower pressure spring to be used if lower pressure is desired, and intermediate shaft
