Tom,

Selecting a radiator and fan shouldn't be that difficult. Allthough all manufacturers use unique approaches to cooling, most of the Mfg's are below in the Mfg section, and all will advise you on which rad and fan to use. FFR uses an OEM Mustang assy.

That being said, if the engine is pumping air into the cooling jacket from a head gasket, head, or block, then not even a diesel truck rad will cool it. Fix the engine first, then the owner, then the radiator.
