Need a V8 Rad
ken5124, brilliant solution.
I have a ~72 radiator in my 65 Dart 273, from Autozone (earliest year they had). It appears it is for a slant six w/ AC. It fits only because I changed to the later aluminum water pump. I did need a 1.5" to 1.75" adapter for the lower tube.
I don't recommend that approach since I had to get the later Federal pwr steering pump and brackets, plus little much room for the fan so couldn't use the clutch fan I bought.
