The radiator does not appear to be moving coolant through it. I put a brand new thermostat in (yes, it's in the right way). The bypass hose on the WP is rock hard. Also, the heater gets really hot but having the heater on full blast does nothing to help cool the engine. What kind fo a mess do I have on my hands here?

You can check for hot or cold spots on the radiator, thermostat housing temp, etc,etc.

You might let the car start to warm up and feel all over the radiator core for cool spots...help see if it has some blocked areas to start with at least. But getting it rodded out if it's a 30-40 year old unit that has never been cleaned might be worth while. If you have no flow though, with the radiator cleaned out...and you know the thermostat is opening a defective water pump could be another thing.
