BBC DS Oil Pump 3-Stage Tri-Lobe RHS MP Mount

The BBC DS Oil Pump 3-Stage Tri-Lobe RHS MP Mount from MOROSO is purpose-built for serious big-block Chevy engine builders seeking maximum oil delivery under high-rpm, high-load conditions. This premium pump addresses one of the most critical aspects of engine performance: reliable, volume-efficient lubrication that prevents bearing wear and catastrophic failure during sustained power output. Whether you're building a street performance engine, a race-focused big-block, or restoring a classic muscle car, adequate oil flow is non-negotiable for longevity and reliability.

This tri-lobe design delivers three distinct pumping stages, each optimized to maintain consistent pressure and flow across the full rpm band while minimizing internal friction losses. The right-hand shaft (RHS) configuration and MP-mount design integrate seamlessly with factory and aftermarket BBC block geometry, eliminating custom fabrication headaches. At 9 pounds and compact 10 x 18 x 8-inch footprint, the pump balances robust internal displacement with practical installation constraints. MOROSO's engineering focus on tri-lobe geometry ensures smooth, efficient oil circulation to main galleries, rod journals, and cam bearings—critical for engines turning 6,500+ rpm reliably.

This pump is ideal for BBC engine swaps, street/strip builds, and restoration projects where original equipment performance falls short of modern demands. The MP mount design offers bolt-on compatibility with standard big-block Chevy timing covers, eliminating extensive machine work. Installers benefit from straightforward plumbing to existing oil galleries and filter systems. Pair this pump with quality aftermarket filters, synthetic oils rated for high-shear environments, and proper gasket sealing to maximize bearing life and engine reliability under sustained load.
