This open chassis "L" style steel wet sump pan is for 1985-earlier Small Block Chevrolet® engines. It is designed for chassis without x-members under the engine (asphalt and dirt modifieds, sprint cars, and some late models). It has an 11-1/2" wide, 16" long, 7" deep "L"”sump with a 9 quart system capacity. Requires use of one of our pickups and an offset aftermarket starter with a 153 or 168 tooth flywheel. Also an avilable option for this pan is #20-914 Pro Louvered Windage Tray, designed to replace the standard screen tray in this pan.
