BBC Oil Pump High Vol. w/H.D. Neck

The BBC Oil Pump High Volume with Heavy Duty Neck from Moroso is purpose-built for high-performance big-block Chevrolet engines that demand reliable, consistent oil delivery under extreme conditions. Whether you're building a street engine, prepping for track duty, or restoring a classic muscle car, this pump addresses a critical need: maintaining adequate oil pressure and flow when stock components fall short. The heavy-duty neck design strengthens the pump's mounting interface, reducing flex and vibration that can compromise seal integrity and oil delivery consistency over time.

High-volume oil pumps increase flow rate—delivering more oil per crankshaft rotation than standard equipment—which is essential when running tighter bearing clearances, upgraded cam profiles, or sustained high RPM operation. The reinforced neck prevents the stress fractures and separation that can occur in stock pumps under aggressive driving, especially in forced-induction or nitrous applications. Moroso's reputation in racing-grade components means this pump meets tight tolerances and delivers consistent performance across temperature and pressure ranges, ensuring your lubrication system keeps pace with your engine's demands.

This pump fits BBC (big-block Chevy) applications from 396 through 454 engines and works with both carbureted and fuel-injected setups. Installation is straightforward—it bolts directly to the engine block using the stock mounting location—making it an ideal drop-in upgrade during engine assembly or rebuild. Pairing it with a quality oil filter, appropriate viscosity oil, and a properly tuned relief valve maximizes protection and longevity, particularly if you're pushing horsepower above 450.
