This radiator is a Direct Fit for all 1966-67 Corvettes with an automatic or manual transmission and LS Motors. Inlet and outlet are on the passenger side. This radiator is designed to fit the original small block core support. This model is oversized compaired to the original, but still fits. It has the pin mounts on the bottom and two small tabs on the front side that eliminates the need for the bracket on the top of the radiator. The stock size radiator fits in the opening of the core support, we designed this radiator so the core of the radiator fills the opening of the core support and the tanks hang off each side. It is almost the same size as the factory BB copper radiator. This radiator features press formed end tanks, dual row core, and serpentine fins. We put a filler neck on the top of the radiator, passenger side, that eliminates the need for the factory Harrison overflow tank and comes with 2 rows of 1" tubes. Automatic transmission applications include 4 plate aluminum transmission cooler, aluminum plate cooler with 3/8" NPT port threads and Jiffy-Tite quick connect fittings included. Aluminum plate style coolers will offer twice the cooling of the OE Copper style coolers. Transmission Cooler is located on the Passenger side.
