SBC Oil Pump Assembly

The Chevrolet Performance SBC Oil Pump Assembly (MPN 14044872) is a high-volume, internal wet-sump oil pump engineered specifically for Small Block Chevy engines. This pump is essential for builders and mechanics upgrading stock oiling systems or assembling high-performance street and race motors. Whether you're restoring a classic, building a modified daily driver, or constructing a serious competition engine, a properly specified oil pump is non-negotiable—it ensures consistent pressure delivery, protects critical bearings, and maintains engine longevity under sustained load.

This assembly features a high-volume design that increases oil flow compared to original equipment, a critical advantage when running tighter bearing clearances, extended RPM ranges, or synthetic oils with different viscosity profiles. The internal wet-sump configuration integrates directly into the engine block, drawing oil from the pan through a 5/8-inch inlet port. High-volume pumps maintain pressure stability across the full RPM band, reducing cavitation risk and ensuring adequate film strength at the crankshaft and cam journals. The compact footprint (4.3 x 4.15 x 6.45 inches) fits standard SBC mounting points without modification, and the 3.92-pound weight reflects a robust, purpose-built construction suitable for sustained performance driving.

This pump is ideal for Small Block Chevy applications ranging from 283 to 400 cubic inches, making it compatible with most vintage muscle cars, hot rods, and modern restomod platforms. Mechanics and engine builders choose this assembly when stock pumps cannot meet flow demands—particularly in boosted applications, roller-cam conversions, or when ambient temperatures and continuous highway cruising demand extra cooling capacity. Installation requires standard engine block prep and timing cover fitment; ensure your pan inlet tube matches the 5/8-inch port specification for seamless operation. Pair with quality synthetic oil and a premium filter for maximum protection and pump longevity.
