Your lower hose should have the coil in it, not the upper. That might be your problem right there, as the coil is designed to prevent the hose from collapsing under suction.

One last thing... Might sound silly... Didn’t you mention pinging as it got hotter? I used to get that in my ‘67, which caused it to run hotter and then ping more and then run hotter and so on. Switching from the never-again-in-my-cars Champion spark plugs to Autolites (#85) solved that for good.

I also just remembered that when I bought the new rad hoses from NAPA and installed them, the both the ones I removed from the Coupe had coils inside to prevent collapse. However, only the top hose from NAPA had a coil. Could this be the problem?

The symptom you described could just as easily be due to failure to pressurize the system, which allows the coolant to boil (and expand!) at normal atmospheric pressure temperature -- 212 degrees.
