Moroso Chevrolet Small Block Louvered Windage Tray

If you're building a Chevrolet small block engine, especially one that's going to see some RPMs, a windage tray is a smart addition. This louvered tray from Moroso is designed to sit between the crankshaft and the oil pan. Its main job is to keep the spinning crankshaft from slinging oil all over the place. By deflecting that excess oil back down into the pan, it reduces windage – that's the drag created by the crank churning through the oil.

This Moroso tray features louvers, which are angled openings that help direct the oil more effectively. This design helps prevent oil from aerating and reduces the parasitic drag on the crankshaft, which can free up a few horsepower and help keep oil temperatures a bit more stable. It's a well-built piece that fits right in place for most small block Chevy applications, making it a popular choice for engine builds where every bit of efficiency counts.

When you're installing this, make sure you have the correct oil pan for your application, as windage trays often work in conjunction with specific pan designs. It’s a straightforward component to add during an engine build or rebuild.
