BBC DS Oil Pump 6-Stage Tri-Lobe RHS MP Mount

The BBC DS Oil Pump 6-Stage Tri-Lobe RHS MP Mount from Moroso is purpose-built for serious big-block Chevrolet engine builders and high-performance enthusiasts who demand reliable, consistent oil delivery under extreme operating conditions. This pump is engineered for applications where stock lubrication systems fall short—whether you're running a supercharged stroker, a dedicated drag racing engine, or a street machine pushing peak boost levels. The right oil pump is foundational; without adequate flow and pressure stability, bearing wear accelerates, ring sealing suffers, and catastrophic failure becomes inevitable.

The 6-stage tri-lobe design increases displacement per revolution compared to conventional 2-stage pumps, delivering superior flow rates across the entire RPM band while maintaining tight internal clearances for minimal slippage and heat generation. The right-hand shaft (RHS) configuration and MP (Moroso Performance) mount accommodate popular BBC block variations and allow straightforward integration into existing engine bay layouts without custom fabrication. Tri-lobe geometry distributes load more evenly across the pump rotor, reducing wear and extending service life in applications where pump speed regularly exceeds 6,000 RPM. This design also generates less cavitation noise and produces more stable outlet pressure, critical for protecting main and rod bearings during high-load acceleration or sustained high-RPM cruising.

This pump excels in big-block Chevrolet engines destined for racing, forced induction, or competition-grade street applications where OEM pump capacity proves insufficient. Compatibility spans a wide range of BBC variants (427, 454, and stroker configurations) when paired with appropriate mounting provisions and driveshaft assemblies. Professional engine builders and experienced DIY technicians typically pair this pump with a quality aftermarket regulator and high-flow filter setup to maximize bearing protection and system reliability. Proper installation includes careful priming before initial startup to ensure air-free operation and immediate oil delivery to critical surfaces.
