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.
