The MELLING BBC HV Oil Pump w/Screen Assembly 91-09 is a high-volume internal sump pump engineered for Big Block Chevy engines requiring robust oil circulation on stock and modified platforms. Built to handle demanding engine speeds and load conditions, this pump assembly ensures consistent oil delivery across the complete 1991–2009 model year range. Designed for serious engine builders and enthusiasts who refuse to compromise on lubrication reliability, this pump delivers the flow and pressure stability that high-displacement applications demand.

This assembly features a spur gear design—the proven workhorse of internal pump architecture—that generates consistent, predictable oil flow without the complexity of variable displacement systems. The high-volume rating maximizes flow capacity, critical for applications where standard pumps fall short under sustained RPM and load. The integrated screen assembly filters debris before oil reaches engine galleries, protecting critical bearing surfaces and extending engine life. Standard pressure relief settings ensure the pump operates safely within OEM parameters while delivering superior volume, eliminating the guesswork from aftermarket upgrades and delivering factory-validated performance.

Big Block Chevy builders—whether pursuing naturally aspirated power, forced induction, or extended RPM limits—benefit most from the MELLING BBC HV Oil Pump w/Screen Assembly 91-09. Installation is straightforward on 1991–2009 Big Block applications; the pump mounts internally within the sump, utilizing OEM mounting locations for hassle-free fitment. Weighing 6.05 lbs with compact dimensions (6.3 x 5 x 11 inches), this assembly integrates seamlessly into tight engine bays without requiring frame or pan modifications.
