I need some help with my cooling system. Im looking for a 22" radiator that will cool the 440 in my 65 coronet. I currently have a 7 blade flex fan and a 3 row summit aluminum rad that just isnt cutting it at idle or slow speeds. Im looking to switch to a stock style clutch fan and shroud and a better radiator. Ive done alot of searching, but most of the radiator suppliers list their products as fitting 66 and up cars. Is there a reason that some of these radiators wont fit a 65? Some of the brands im looking at are OER, Griffin & Wizard.
