Product Details

The Moroso 20405 is a high-performance wet sump stroker oil pan engineered specifically for Chevy Big Block Mark IV engines. This 8-inch deep steel oil pan is designed to accommodate stroker crankshafts while providing superior oil control for street performance and drag racing applications.

Key Features:

  • Constructed from steel with clear zinc finish for durability and corrosion resistance
  • 6-quart oil capacity for extended engine protection
  • Modified front sump design accepts stroker cranks up to 4.625" stroke with steel connecting rods or 4.250" stroke with aluminum rods
  • Trap door baffling system provides improved oil control during acceleration and deceleration
  • Kicked-out sump design offers additional ground clearance
  • Includes magnetic drain plug for capturing metallic debris
  • Compatible with most starter and flywheel combinations
  • Hand-welded fabrication made in Guilford, Connecticut

This oil pan fits most chassis configurations for Big Block Chevy Mark IV engines (excluding Gen V and Gen VI variants), though crossmember modification may be required for proper front sump clearance. Recommended for use with Moroso oil pump pickup #24440 or #24441 for optimal performance.
