The Pontiac Screen Windage Tray sandwiches between block and the pan. Made to be used with the 301-455 blocks and aftermarket pans that are deeper in the front than OE.
The half-screen, half-solid design offers superior oil control and horsepower savings when compared to previous designs. This full-length tray wraps around the oil pump and provides windage control for the entire rotating assembly. The rail mounted design eliminates the need for mounting studs and allows installation on engines not originally equipped with stock trays.
