BBC Hi-Volume Oil Pump

The MELLING BBC Hi-Volume Oil Pump (Part Number 10770) is a high-pressure internal wet-sump oil pump engineered for Big Block Chevy engines requiring elevated flow rates and sustained pressure delivery. This pump is purpose-built to support aggressive engine builds, racing applications, and high-displacement powerplants where factory oil circulation is insufficient. The 3/4-inch inlet accommodates standard wet-sump oil pan configurations, making installation straightforward on compatible BBC platforms.

High-volume oil pump design increases flow capacity compared to stock units, ensuring adequate lubrication and cooling under sustained high RPM and high-load conditions. Elevated pressure delivery protects critical bearing surfaces, cam lobes, and valve lifters during extended acceleration and continuous power output. The internal pump configuration integrates directly into the engine block, eliminating external mounting complications and maintaining a compact installation footprint. For Big Block Chevy applications, this MELLING pump delivers consistent performance across racing fuel injection systems, supercharged builds, and long-duration cam profiles where oil starvation poses reliability risks.

Builders and engine shops specify high-volume oil pumps when transitioning from stock displacement to aftermarket rotating assemblies, aggressive valve timing, or turbo/supercharger applications. This pump addresses the flow demands of modern Big Block performance builds without requiring extensive modifications to existing pan and pickup tube configurations. Each unit is individually supplied for direct replacement or performance upgrade installations.

MELLING is a recognized manufacturer of OEM and performance engine components with decades of heritage in pump design and internal engine systems. Sourcing a verified BBC hi-volume oil pump from an established brand ensures compatibility with documented Big Block specifications and pressure curve specifications.
