BBC Std. Volume Oil Pump

The Melling BBC Standard Volume Oil Pump (Part No. 10774) is a wet-sump internal oil pump engineered for big block Chevy engines requiring reliable, consistent lubrication under high pressure. This standard-volume pump delivers the flow rate and pressure stability essential for engines operating at elevated RPM, whether in street applications, performance rebuilds, or marine duty where sustained engine protection is non-negotiable.

Equipped with a 3/4-inch inlet, this pump integrates seamlessly into conventional wet-sump systems where the pump draws oil directly from the pan. The high-pressure design ensures adequate oil distribution to main bearings, rod journals, and valve train components under load, preventing starvation during acceleration and sustained cruising. Melling's manufacturing process prioritizes dimensional consistency and internal flow characteristics, critical factors that directly influence bearing life and engine durability across thousands of operating hours.

Big block Chevy builders and marine engine technicians select this pump for restorations, replacement rebuilds, and performance upgrades where OEM-specification flow and pressure recovery are required. It serves engines from street builds to towing and boating applications where thermal stability and consistent lubrication prevent catastrophic bearing wear. The pump arrives as a complete unit, ready for installation into a prepared block with matching pan and pickup configuration.

Standard-volume pumps balance flow output with parasitic drag, making them ideal for naturally aspirated big block engines where maximum oil delivery meets practical power-loss constraints. Forced-induction or extreme high-RPM applications may require high-volume alternatives; verifying your specific engine's pressure and flow requirements before installation ensures optimal performance and longevity.

Weighing 5.25 lbs and measuring 5.8 × 4.7 × 6 inches, this pump is engineered to exact Melling specifications for BBC applications and carries UPC 729295513308 for easy identification and inventory management.
