BBC Ext Oil Pump RHS MP Mount Tri-Lobe FP Drive

The BBC Ext Oil Pump RHS MP Mount Tri-Lobe FP Drive from MOROSO is a high-performance external oil pump engineered for big-block Chevrolet engines requiring reliable, consistent oil delivery during extreme competition and street performance applications. This pump addresses the lubrication demands of modified BBC powerplants where factory internal pump capacity falls short, ensuring adequate oil pressure and flow to critical bearing surfaces during sustained high RPM operation. Designed for right-hand-side mounting with multi-port compatibility, it integrates seamlessly into custom engine builds where packaging flexibility and superior circulation are non-negotiable.

The tri-lobe rotor configuration delivers efficient, smooth pumping action with minimal pulsation, a critical advantage when feeding oil galleries under load. The MOROSO FP (full pressure) drive system ensures the pump operates at optimal speed ratios relative to engine RPM, maximizing flow without sacrificing component longevity. Built with precision machining and heavy-duty construction, the 5.155 lb casting and compact 7 x 7 x 8 inch footprint provide durability while maintaining a tight engine-bay envelope—essential for tight-fitting BBC installations where space is limited. The external configuration also permits independent pump maintenance without disturbing the engine block.

This pump benefits drag racers, circle track competitors, and serious street performance builders running modified BBC engines with aggressive cam profiles, high boost pressure, or extended operating windows where stock oil delivery proves inadequate. Installation requires compatible drive pulley and belt routing configured for right-hand-side mounting; verify clearance and drive compatibility with your specific BBC variant before purchase. The tri-lobe design works across a wide range of engine sizes within the big-block family, making it a versatile upgrade for any high-output BBC application demanding race-proven reliability and superior pressure stability.
