Moroso Performance Oil Pan (MPN: 21813)

High-capacity oil pan designed for small block Chevy engines.

The Moroso Performance Oil Pan is engineered specifically for 1980 and earlier small block Chevy engines, accommodating up to a 4.125 inch stroke with steel rods. This 7 quart capacity oil pan features a left side dipstick and a wet sump design, making it suitable for both road racing and drag racing applications. The 7-1/2 inch deep sump includes three trap door baffles and two runners for optimal oil control, ensuring reliable lubrication under high-performance conditions.

Constructed from durable steel and finished with a powder-coated black exterior, this oil pan is built to withstand the rigors of racing. The integrated crank scraper and removable screen windage tray enhance horsepower by reducing oil aeration and slosh.

In addition to the oil pan, Moroso offers a comprehensive range of oiling system accessories, including oil pumps, pickups, and windage trays, all designed to work seamlessly together. This integrated approach allows engine builders to customize their setups for maximum performance, making the Moroso Performance Oil Pan a reliable choice for serious racers.
