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

I bought a 64 dart with overheating problem and found the lower radiator hose had a plastic plug inside causing restricted flow
Well, @RustyRatRod, here we go again. Somebody partially blocked the flow in the radiator hose to "help" an overheating problem. Because we all know that the water has to move slowly through the radiator, right? :thumbsup::BangHead::BangHead:
It seems like we were just discussing this a few weeks ago.
