Reproduction 3 Core radiator for the 1967, 1968, 1969, and 1970 with the 390, 427, and 428 as well as the 1970 351 Cleveland and 351 Windsor.
For the 1967 - 1969 FE / Big Block Cougar and Mustang and 1970 351c & 351W with AC and or heavy duty cooling package. For optimum cooling you will want to purchase a shroud as well. Most Cougars these days have been bored .030 or more and many have had performance upgrades which all lead to increased heat. Before you buy fancy wheels, valve covers or most anything else (except brakes) this should be at the top on your list. Many applications only call for a 2 core but we feel more is better especially when the price is the same.
*Note - This radiator is not correct for the 1967 390 but will work fine if you use the 68-70 lower cradle mounts.
