Fits Chrysler 383-440 Big Block with Up to 4.15 Inch Stroke

This windage tray includes molded rubber gaskets on the top and bottom for a one-piece design. The windage tray is made from glass filled nylon & molded rubber (modern materials that hold up to heat & oil). The molded rubber gaskets don't need any RTV (room temperature vulcanizing), so future service is easy (no scraping off old gaskets and replacing them each time the oil pan is removed). The re-usable windage tray / gasket can be washed with soap & water. Made in the USA.
