  • Clear zinc steel construction for Chevy big-block Gen IV

Deep Front Sump Oil Pan

The Moroso 21048 is a drag-race oil pan built for Chevy big-block Gen IV engines. Its deep front sump design improves windage control during hard acceleration. A louvered steel tray separates oil from crankcase air for consistent lubrication. The pan holds seven quarts and measures eight inches deep at the sump.

Upgrade From Shallow Factory Pans

Factory shallow sumps allow oil to climb the block under launch G-forces, starving the pickup. This pan replaces that layout with a deep front sump and partitioned tray that keeps oil at the pickup. The jump is worth it when the car sees repeated hard launches or sustained high-RPM runs on the strip.

Suits Drag Racers With Big-Block Chevys

Racers running Chevy big-block Gen IV combinations in dedicated drag cars will benefit from the windage control and capacity. Builders using other engine families, street-driven vehicles, or classes that mandate stock-appearing pans should look at something else. The clear zinc steel finish resists corrosion but is not a show-polished surface.
