BBC 2pc. Billet Rail Oil Pan

The MOROSO BBC 2pc. Billet Rail Oil Pan (MPN 20376) is a purpose-built engine oil containment system designed for Big Block Chevy platforms in street and strip applications. This two-piece aluminum construction addresses the cooling and capacity demands of high-performance and endurance driving where standard factory pans fall short. Built by Moroso—a trusted name in racing and performance engine components—this rear-sump configuration delivers the reliability and capacity serious enthusiasts and professional mechanics demand.

Engineered with a 7-quart capacity and 8-inch depth, the BBC 2pc. Billet Rail Oil Pan maximizes oil volume while maintaining a low profile—critical for street/strip vehicles running tight engine bays or competition setups. The two-piece sealed design allows for precise fitment and easier service without full pan removal in many instances. Constructed from lightweight aluminum with a natural finish, the pan resists corrosion and distributes heat efficiently during sustained high-RPM operation. The rear-sump configuration positions the oil pickup for optimal suction geometry, reducing aeration and ensuring consistent oil delivery to the engine during aggressive acceleration, hard cornering, and extended track use.

This pan is ideal for Big Block Chevy engine swaps, dedicated race cars, and modified street machines where cooling capacity and reliability matter. Installation requires engine-bay clearance assessment—the 17.25 x 10 x 26.5-inch footprint fits most BBC applications, though custom headers or tight undercarriage geometry may require adapter fitment. The two-piece seal system accommodates both standard and aftermarket oil pump pickup tubes, making it compatible with most BBC fuel-injection and carbureted builds. At 23 pounds, the aluminum construction saves weight over cast-iron factory units while maintaining structural integrity under sustained load.
