BBC Ultra-Pro Alum. Dry Sump Oil Pan

The BBC Ultra-Pro Aluminum Dry Sump Oil Pan from MOROSO is engineered for serious Big Block Chevrolet engine builders who demand superior oil control and cooling in high-performance applications. Dry sump systems are essential for race cars, forced-induction builds, and extreme duty vehicles where conventional wet sumps fail to manage oil supply under sustained lateral g-forces, high RPM operation, or tight engine bay packaging. This aluminum pan delivers the reliability and efficiency that professional mechanics and dedicated enthusiasts require when building competition engines or heavily modified street machines.

Constructed from lightweight aluminum, the Ultra-Pro pan reduces unsprung mass while maintaining structural rigidity—critical for weight-sensitive race applications. The dry sump design incorporates dedicated scavenging galleries and optimized baffling to continuously extract oil from the pan and return it to an external tank, preventing starvation during cornering, acceleration, and deceleration. This design also improves cooling efficiency by cycling fresh oil through the system and eliminates the oil surge common in wet sumps at high cornering speeds. The 17.5-pound weight penalty is far outweighed by the performance gains in oil pressure stability and engine longevity during sustained high-load operation.

This pan is purpose-built for Big Block Chevrolet applications and integrates seamlessly with complete dry sump systems or hybrid configurations. Professional engine builders, drag racers, road course competitors, and high-horsepower street enthusiasts benefit most from this upgrade when paired with a matching pump and tank assembly. Installation requires removal of the original oil pan and connection to the dry sump pump feed and return lines; compatibility with existing engine mounts and suspension geometry should be verified during planning stages. MOROSO's reputation for precision manufacturing ensures fitment accuracy and durability through thousands of engine cycles.
