Moroso 20404 Street/Strip Oil Pan Big Block Chevy Mark IV 8-Inch Deep

The Moroso 20404 is a high-performance wet sump oil pan engineered for Chevrolet Big Block Mark IV style engines. Hand-fabricated from heavy-gauge steel at Moroso's Guilford, Connecticut facility, this pan is built to deliver reliable oil control for street performance and occasional strip use.

Designed as part of Moroso's legendary BBC Mark IV oil pan series, the 20404 features a kicked-out or deep sump design that increases oil capacity and improves oil retention under hard acceleration, cornering, and braking. Internal baffling and trap door technology help keep oil at the pump pickup under demanding conditions.
