BBC Diamond Screen Tray

The BBC Diamond Screen Tray from MILODON is a precision-engineered windage tray designed specifically for Big Block Chevy engines. This steel component manages oil flow and crankshaft windage in high-performance and racing applications where engine efficiency directly impacts overall vehicle performance. The diamond stripper design reduces turbulence and parasitic drag, allowing the engine to produce maximum power while maintaining consistent oil pressure throughout the lubrication system.

Manufactured from durable steel with cadmium plating for corrosion resistance, the BBC Diamond Screen Tray features a strategically perforated diamond pattern that separates oil mist from circulating oil while preventing excessive aeration. This design philosophy minimizes horsepower loss caused by crankshaft churning and windage resistance—critical considerations in serious engine builds. The cadmium finish provides long-term protection against rust and degradation, ensuring reliable performance across extended engine operation and demanding driving conditions.

Enthusiasts building or rebuilding Big Block Chevy engines—whether for street performance, drag racing, or naturally aspirated high-output applications—benefit significantly from this windage management solution. Installation is straightforward as an engine assembly component, and the tray integrates seamlessly with stock and aftermarket pan configurations. This is an essential upgrade for builders seeking measurable improvements in parasitic drag reduction and reliable oil management in competition or high-revving environments.
