1963-1972 DeWitts Radiator and Fan LS Series Engine Retro Fit Kit - OEM Number(s) (3155316)

Mid America Motorworks now offers DeWitts special 1963-1972 LS Series Corvette Radiators that are built to fit the stock 1963-1972 2 pin style small block core support but configured to hook up with a newer LS series engine. High performance 16" Spal fan is mounted directly to the radiator, eliminating the need for the factory fan and shroud. Relay and wiring harness is also included in each package. Connection sizes are changed to match the ports on the LS engine. We also include a connection for the steam line and install the fan switch into the end tank. Precision fit full shroud features 6 air check flaps to prevent high frontal air pressure buildup at high speed.

The Radiator Core measures 17" tall by 22-3/4" wide, 3" thick, and 6" thick with fan included.
