Cooling Issue - 1964 Dart GT - 273 with automatic and A/C

Just a side fact about the 1964 Dart radiator: Since the V8 was a late addition to the '64 Dart they did not use a different radiator support panel than the /6. Therefore the radiator is noticeably off center with the fan blade on '64 273 V8's. The fan blade overhangs to one side.
But I doubt if this is part of the author's issue since my '64 V8 Dart doesn't get that hot even on 100 deg. days.
