Product Details

The Moroso 20431 is a notched rear sump oil pan designed specifically for small block Chevrolet engines in street performance and racing applications. This fully fabricated aluminum pan features a deep sump design that increases oil capacity while maintaining proper oil control to keep the crankshaft free of excess oil, allowing the engine to spin freely and achieve maximum power potential.

Key Features:

  • Notched rear sump design for improved ground clearance and chassis compatibility
  • Deep sump wet sump configuration increases oil capacity for better cooling and lubrication
  • Accommodates stroker crankshafts up to 4.250" stroke with steel connecting rods, or 4.090" stroke with aluminum rods
  • Compatible with most starter and flywheel combinations
  • Fully fabricated aluminum construction for strength and light weight
  • Race-proven features that control oil under high-performance conditions
  • Core charge applies (core-based product)

This oil pan is engineered for street performance, drag racing, oval track, and road racing applications where enhanced oil control is critical. The rear sump design positions the oil pickup toward the back of the pan, making it ideal for vehicles with rear-wheel drive configurations and engines mounted in front-engine chassis layouts.
