BBC Pro-Plus Windage Tray

The CANTON BBC Pro-Plus Windage Tray is a louvered steel windage tray designed specifically for Big Block Chevy engines running rear sump oil pan configurations. This windage tray mounts beneath the crankshaft to deflect oil splash and reduce windage losses—a critical component for builders seeking to maximize power output and engine efficiency in high-performance applications.

Constructed from zinc-plated steel, the tray features a louvered design that separates aerated oil from the crankshaft while preventing oil from clinging to rotating components. The louvers channel oil back to the sump efficiently, reducing drag on the crankshaft and allowing more horsepower to reach the wheels. Proper windage management becomes increasingly important in engines operating at sustained high RPM or heavy boost, where oil aeration directly impacts lubrication reliability and parasitic loss. At 3.2 lbs, the Pro-Plus design adds minimal weight while delivering measurable efficiency gains.

This windage tray is engineered for Big Block Chevy platforms—including street engines, race engines, and forced-induction builds. Whether building a carbureted big-block for cruise nights or a turbocharged engine for track duty, controlling crankcase turbulence protects the engine's lubrication system and extends component life. The rear sump configuration ensures compatibility with OEM and aftermarket pan designs commonly used on BBC applications.

CANTON windage trays are recognized in performance engine building circles for solid engineering and real-world effectiveness. The Pro-Plus model represents the refined version of CANTON's proven design, delivering consistent results across diverse BBC builds from mild restorations to serious competition engines.
