Moroso Chevrolet Big Block Mark IV Windage Tray (For Part No 20485/20385 New Style)

This is the Moroso windage tray specifically for Chevrolet Big Block Mark IV engines using their new style oil pans, part numbers 20485 or 20385. A windage tray is a crucial component that sits between the crankshaft and the oil pan. Its main job is to reduce the amount of oil that gets slung around by the rotating crankshaft.

By minimizing this oil splash, the windage tray helps prevent the crankshaft from having to push through a mist of oil. This can lead to improved engine performance by reducing parasitic drag, allowing the engine to rev more freely. It also helps keep the oil in the pan cooler and can contribute to better oil control within the crankcase. This particular tray is designed to work with specific Moroso oil pan part numbers, ensuring a proper fit and function within your engine build.
