SBC Dry Sump Oil Pan CT Asphalt LM

The MOROSO SBC Dry Sump Oil Pan CT Asphalt LM (MPN 21545) is a purpose-built dry sump oil pan engineered specifically for Small Block Chevy engines running in circle track and asphalt racing environments. This aluminum pan is designed for racers and performance builders who demand reliable oil management under sustained cornering loads, high-G acceleration, and the extreme demands of late-model asphalt competition. Dry sump systems eliminate the weight penalty and chassis packaging constraints of traditional wet sumps, allowing teams to optimize weight distribution and fuel cell placement.

Constructed from lightweight aluminum, this two-piece seal design delivers a 5-quart capacity with a 4.25-inch pan depth, providing adequate oil volume while minimizing sump height for tight engine bay configurations. The left-hand port arrangement optimizes return line placement for asymmetrical race car layouts common in Port City Asphalt and similar short-track series. The compact 15.25 x 8.38 x 22.38-inch footprint (11.9 lbs) ensures fitment in space-constrained racing applications without sacrificing functionality. The natural aluminum finish resists corrosion in high-temperature engine environments and allows easy visual oil level monitoring through the sump.

This pan is ideal for Small Block Chevy racers competing in asphalt late-model classes where consistent oil delivery is critical to engine longevity and performance. Installation requires coordination with a dry sump pump system and return lines, making it essential to verify compatibility with your existing pump setup and tank configuration. The left-hand port designation is not universal—confirm that your scavenge and return line routing accommodates this specific pan orientation before purchase to avoid costly fitment errors.
