Oil Pan GM LT Eng. Swap Drainbacks Cast Alm.

The Oil Pan GM LT Engine Swap Drainbacks Cast Aluminum by MOROSO is purpose-built for engine builders and performance enthusiasts executing LS/LT engine swaps into non-GM platforms. This specialized oil pan addresses one of the most common challenges in engine transplants: proper oil return routing and reservoir capacity when working with modern GM's lightweight, efficient LT powerplants. Whether you're dropping an LT into a classic muscle car, hot rod, or custom chassis, this pan eliminates fabrication headaches and ensures reliable oil circulation under all operating conditions.

Cast aluminum construction provides excellent heat dissipation while maintaining structural rigidity under high-G cornering and acceleration loads. The integrated drainback passages allow excess crankcase pressure and oil mist to return efficiently to the reservoir, preventing buildup that can compromise ring sealing and increase crankcase vacuum. MOROSO's engineering accounts for GM LT engine geometry—including the unique valley casting and oil delivery pathways—ensuring compatibility without modification to your engine block or mounting surface. At 18.75 pounds, the aluminum design keeps rotating assembly mass minimal while delivering the durability required for street and track applications.

This oil pan is ideal for LT1, LT4, LT5, and LT6 engine swap projects where factory GM pans prove incompatible with custom chassis layouts. Installers benefit from the proven drainback design, which eliminates the need for external air/oil separation systems in many swap scenarios. Verify clearance with your specific frame, suspension, and steering geometry before purchase, as swap installations vary widely; the 12 x 7 x 24-inch footprint accommodates most traditional front-engine configurations. Professional builders and weekend warriors alike trust MOROSO's reputation for precision casting and fitment accuracy in the engine swap community.
