DeWitts LS HP SERIES Radiator w/ Dual 11" SPAL Fans [2 ROW | 1" TUBES | BLACK ICE | AUTOMATIC] (1963-1965 Chevrolet Corvette LS)

This radiator is custom-made to simplify a LS series engine conversion on 1963-72 Corvettes. First, we moved the inlet and outlet to the passenger side. These connections are resized to match the ports on the LS engine. Second, we added a filler neck for a direct-mounted radiator cap, which eliminates the need for a separate surge tank. We even added 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 2720 CFM airflow. 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.
