Hi all: Sometimes the wrong radiator core is installed. Several years ago, Big John McAdams had heating up problems in his '62 Sport. I have the same engine (413) in my 300F and have never experienced any heating problems, even going over the Rockies with the air going full blast. I counted the number of fins per inch in his radiator (16) and the number in my original 300F (19) As I recall, he changed out his radiator to one of 19 fins per inch and helped his problem.
