BBC DS Oil Pump 5-Stage Tri-Lobe RHS MP Mount

The MOROSO BBC DS Oil Pump 5-Stage Tri-Lobe RHS MP Mount is a high-performance oil circulation system engineered for big-block Chevrolet engines running competition fuel systems or modern EFI conversions. This pump is built for serious engine builders and racers who demand superior oil delivery at elevated RPM ranges and need right-hand shaft orientation compatible with MP (mechanical pump) mounting configurations. Whether you're building a street performance engine or a dedicated race motor, this tri-lobe design ensures consistent pressure and flow that stock pumps simply cannot deliver.

The five-stage tri-lobe rotor design generates superior volumetric efficiency compared to traditional gear-type pumps, delivering more oil at lower displacement and reducing parasitic drag on the crankshaft. The tri-lobe configuration creates a smoother pressure curve with less ripple, which translates to quieter operation and reduced bearing wear under sustained high-RPM conditions. MOROSO's precision manufacturing ensures tight tolerances that maintain efficiency across a wide range of oil viscosities and engine temperatures, while the RHS shaft orientation integrates seamlessly with right-handed fuel system mounting blocks common in BBC installations.

This pump is ideal for BBC engines equipped with aftermarket fuel systems, big-displacement stroker builds, or applications where OEM pump capacity proves inadequate. The MP mounting interface accepts standard mechanical drive shafts and couples directly to BBC timing cover bosses without modification. Installation requires basic mechanical knowledge and familiarity with BBC plumbing; confirm your specific shaft length and fuel system compatibility before ordering, as pump configuration depends on your engine's accessory drive layout and intended duty cycle.
