This custom Thermostat Housing is machined from billet aluminum. Its 2-piece design allows it to fully rotate to perfectly fit for your particular application. This Scott Drake exclusive was designed for classic car applications that require a 45 degree angle. Do not confuse this with the common 90 degree angle version used on later model applications. Will fit 260, 289, 302 and 351W engines installed on most 1960 and 1970 Ford Cars and Trucks. Rubber O-Ring Seals ensure a leak proof installation and comes with mounting hardware.
