Upper Radiator Hose Pressure??

Overflow Tube is Clear, Rad Cap is old.

Not showing any moisture on the dipstick or in the oil.

It's Just weird, all my other cars while running, I can squeeze the upper radiator hose and it will squeeze, but not this one, even right after starting. From the time it takes me to start the car, to walk to the front of the car and squeeze the hose, it's full of pressure. The Car Sat for almost 10 years before I got it. Changed the oil, filter, replace all the electronic stuff from Ignition control module to ballast resistor to battery cables and starter and wires and plugs and cap and rotor. Even got a new Fuel tank and Pump and carb rebuilt before starting it for the first time in 10 years. Once it was all replaced she fired right up and purrs like a kitten. Did not replace the Water pump however and when I got it, the Radiator was completely dry.
