So- I have a '73 with a 4v 351c. I just got some cooling issues taken care of and now I want to tackle the heater. I have one hose that goes directly from the block to the heater core. The water pump actually has two ports but one is blocked off. And of course, the other port is connected to the other inlet/outlet of the heater core. Is this correct? After driving the upper radiator hose is too hot to hold but the heater hose is just warm. And when I turn on the heater or defroster, it's just ambient temperature.
