I have a champion 3 row in my 440 dart....it's barely able to keep it cool. Hot texas days it'll creep to 220. I know there's many variables that can cause this...but I'm fairly certain this radiator doesn't have the cooling capacity needed. Fixed Fan, no Clutch, shroud, hood seals in place. Creeps in town and at high ways speeds. I seem to recall finding out the rows are .675"....which is SMALL.
