dodge ram overheats

My 1983 dodge ram 318 cu in engine overheats after driving about 20 minutes. I notice the top radiator hose very tight like thermostat stuck. I removed it and it did it again. So I replace radiator cap and still the top hose gets very tight when I notice overheating. I installed new radiator a couple of years ago and put on new water pump about a year ago, so I don't think the radiator is plugged. Could my engine jacket be plugged?

When you say the radiator hose get very tight I'm guessing you mean with pressure. If it pressurizes very quickly from cold it may be from a head gasket leak putting gasses into the cooling system. Top rad hose should stay cool till thermostat opens and will be too hot to hold and you will feel the air from the fan warm up. If that's not happening coolant can't flow.
Check that coolant is staying full at radiator cap and reservoir,
