BBC Alum Short V/C Ball Milled Polished

The BBC Alum Short V/C Ball Milled Polished valve covers from Racing Power Co-Packaged deliver a refined, professional appearance while managing crankcase ventilation on Big Block Chevy engines. This pair combines aesthetic appeal with functional venting—the ball milled finish creates distinctive visual texture across the aluminum casting, while the polished surfaces catch light and enhance engine bay presentation. At 2.563 inches in height, these short-profile covers fit tight engine compartments without sacrificing breather functionality or interference with common headers and accessories.

Constructed from aluminum and finished with both ball milling and polishing, these covers incorporate breather holes integral to proper crankcase evacuation on high-performance engines. The baffled internal design helps separate oil vapor from exiting air, reducing oily residue in intake tracts and improving combustion efficiency. All mounting hardware is included, so assembly and installation require no additional fasteners. The short valve cover profile allows builders to work within tight packaging constraints while maintaining the dual-cover setup Big Block applications typically require.

This pairing is built for street and strip engines where both performance and visual finish matter—restoration projects seeking OEM-style appearance with modern materials, engine swaps into compact engine bays, and builders prioritizing crankcase management without oversized covers. The ball milled and polished aluminum resists corrosion better than traditional cast iron, and the finish remains maintainable with standard detailing. Weighing 7.8 lbs per pair, these covers are lightweight components that do not burden fuel economy or handling balance.
