The Scott Drake high performance 2-core aluminum radiator is the ultimate cooling solution for 1964.5-66 Mustangs running a late model 5.0L V8. These heavy-duty radiators feature extra large 1" tubes for 4 row efficiency without the added bulk and weight. The also are equipped with the Scott Drake exclusive baffle on the top tank to help evenly distribute the flow of hot water through the radiator. Original radiators had a serious problem distributing the hot water to the far right side of the radiator. This baffle design has been extensively tested and recorded significant changes in the temperatures across the radiator's cooling tubes. This radiator is equipped with integrated automatic transmission cooling lines and a brass petcock drain. For use with auto or manual trans cars.
