High-Performance Aluminum Radiator for 1967-1970 Big Block 390-428 models and 1970 302, 351 models with heavy duty cooling. It features a transmission cooler that will provide improved performance from its extra large 2 row 1" tubes that equal 4 row efficiency but with 5-7 lbs. less weight. This radiator offers a substantial savings over traditional copper/brass 4 row radiators. Also fits 1967-1969 with late model 5.0L engines. For a hassle free installation please use Scott Drake's Radiator Insulator and Mount Brackets specifically designed for this Aluminum Radiator. Note: On 1967 Mustangs you are required to drill an additional hole to mount lower brackets. Not compatible with factory fan shroud.
