This radiator is custom made to simplify a LS series engine conversion on 1963-65 Corvettes. First, we move the inlet and outlet to the passenger side. These connections are resized to match the ports on the LS engine. Second, we add a filler neck for a direct mounted radiators cap, which eliminates the need for a separate surge tank. We even add a connection for the steam line. This radiator is designed to fit the original small block (pin mount) core support and it will eliminate the stock upper mounting bracket. This larger package will fill 100% of the core support opening with functioning core area while the end tanks are on each side behind the support. Pre-mounted to the radiator are Spal dual 11" electric fans, providing 2780 cfm air flow. This will eliminate the factory fan and fan shroud. The fans will be controlled via a 195on/175off temperature switch, which we mount inside the end tank. Wiring harnesses, relays and wiring instructions are also included.(Note: The horn relay and voltage regulator must be relocated on 1963 models)
