BBC Gen IV Stock Oil Pan

The MOROSO BBC Gen IV Stock Oil Pan (part number 20449) is designed specifically for big-block Chevy Gen IV engine platforms, serving as a direct replacement for factory lubrication systems. This oil pan is essential for mechanics working on high-performance big-block builds, whether restoring original specifications or transitioning from modified sump geometry back to OEM-compliant capacity.

Constructed from robust steel, this pan maintains the factory footprint while ensuring proper oil return and breather integration. It includes provisions for the standard dipstick tube and pickup tube mounting, preserving the original engine bay layout and simplifying installation. The pan's design prioritizes accurate casting to handle consistent engine operation.

Street and strip builders will appreciate the bolt-on compatibility with existing engine blocks, eliminating the need for custom fabrication. With its length accommodating the wide stance of big-block platforms, this oil pan fits within typical engine compartment boundaries, making it a practical choice for restorations and street applications.
