Moroso Performance Oil Pan (MPN: 20385)

Engineered for Drag Racing with Advanced Oil Control Features

The Moroso Performance Oil Pan is specifically designed for Mark IV Big Block Chevy engines, accommodating up to a 4.75 inch stroke with aluminum rods. This oil pan features a capacity of 7 quarts and incorporates a double kick out design that ensures ample stroke clearance and wide main cap clearance, optimizing horsepower and performance. Constructed from fully fabricated aluminum, it utilizes a race pan rail bolt pattern for secure installation and reliability.

The solid louvered tray with main cap partitions enhances oil control and power delivery, making it a critical component for serious drag racing applications. The sump design is compatible with Moroso spur gear and gerotor billet oil pumps, ensuring efficient oil circulation. Additionally, the billet end seals provide a consistent sealing surface to both billet front covers and rear main caps, further enhancing the oiling system's integrity.

With an 8 inch sump depth and 9-7/8 inch sump length, this wet sump oil pan is baffled to prevent oil starvation during high-speed maneuvers. The rear sump position and included windage tray contribute to effective oil management, while the dipstick provision on the passenger side allows for easy monitoring of oil levels. Moroso's commitment to quality and precision engineering ensures that this oil pan meets the rigorous demands of competitive racing.
