Oil Pump, Standard-Volume, Chevy, Small Block

*Chevy 400 engines require the oil pump driveshaft opening to be machined to a 9/16 in. diameter

Moroso "Race" Oil Pumps are designed to accommodate consistent oil pressure and volume requirements for today's racing engine

Moroso engineers' anti-cavitation grooves into the pump housing to prevent pump chatter, which will lead to broken pickups and inconsistent oil pressure

Anti-cavitation slots are machined to bleed oil back to the inlet side of the pump, and an enlarged bypass area ensure a smooth flow rate throughout any RPM range
