BBC Oil Pan Dry Sump w/4-Pickups Aluminum

The MOROSO BBC Oil Pan Dry Sump w/4-Pickups Aluminum (MPN 21582) is purpose-built for serious big-block Chevrolet performance enthusiasts who demand maximum oil control and reliability under extreme conditions. A dry sump system eliminates traditional oil slosh and windage losses that plague conventional wet-sump pans during high-RPM acceleration, cornering, and sustained racing. This design is essential for engine builders and racers who run tight clearances, high oil temperatures, or aggressive driving dynamics where maintaining consistent oil supply to critical bearing surfaces directly impacts engine longevity and peak horsepower delivery.

Constructed from lightweight aluminum, this pan integrates four strategically positioned pickups that scavenge oil from the sump and route it back to the remote reservoir, ensuring steady flow regardless of g-forces or driving angle. The aluminum construction reduces unsprung weight compared to cast-iron alternatives, lowering both the vehicle's center of gravity and inertial mass—critical advantages in competition applications. The multi-pickup design prevents oil starvation at the main and rod bearings by maintaining consistent pressure delivery, while the sealed aluminum pan resists corrosion and allows for cleaner engine bay aesthetics. Measuring 17.5 x 10 x 26 inches and weighing 17.285 lbs, the pan fits within typical BBC engine bay constraints while maintaining the structural rigidity required for high-boost or nitrous applications.

This dry sump pan is ideal for BBC-powered drag cars, road-race platforms, and street performance builds where engine reliability under load takes priority. Installation requires a compatible dry sump pump and remote reservoir kit, along with proper plumbing to the oil cooler and return lines—a setup favored by serious engine builders and race teams. Verify clearance with your specific engine block, cylinder heads, and chassis configuration before ordering, as BBC applications vary widely across Chevrolet generations and custom builds. MOROSO's proven engineering and quality aluminum construction make this pan a trusted choice for competitors who refuse to compromise on oil system performance.
