BBC 11qt Wet Sump Oil Pan Straight Box Sump

The BBC 11qt Wet Sump Oil Pan Straight Box Sump by MOROSO is engineered for serious big-block Chevrolet engine builders and hot rod enthusiasts who demand reliable oil management in high-performance applications. This wet sump design is the foundation of any street or strip engine that requires consistent lubrication during sustained rpm and aggressive driving. Built by MOROSO—a brand trusted by professional mechanics and fabricators—this oil pan delivers the capacity and geometry needed for engines that push limits without compromising oil pressure stability or circulation.

The straight box sump configuration maximizes usable oil volume at 11 quarts, allowing the oil to pool efficiently while minimizing foaming and aeration—critical factors when running tight clearances or extended throttle sessions. The sump geometry is engineered to keep the pickup tube submerged under lateral g-forces, preventing starvation that can lead to bearing failure or catastrophic engine damage. Steel construction with precision welding ensures durability under thermal cycling and vibration, while the design integrates with standard BBC mounting points for straightforward installation without custom fabrication or modifications to existing engine bays.

This pan is ideal for BBC-powered street rods, restorations, race cars, and performance trucks where factory or undersized pans create oil pressure issues or temperature problems. Mechanics and engine builders rely on MOROSO pans because they integrate seamlessly with bolt-on components—headers, sump gaskets, and pickup assemblies all work within proven tolerances. Whether you're building a weekend cruiser or a competition engine, the BBC 11qt wet sump pan provides the oil capacity and reliability needed to keep your big-block running strong through thousands of miles.
