Something doesn't make sense here Nathaniel. I've isolated 4 statements from you below.

If the temp sensor which is just downstream from the thermostat is seeing 210 degrees and
If the thermostat is working and
If the upper hose is cold and
If the coolant is flowing through the upper hose
... the where is the heat going?
By the way, I assume the autometer sensor is feeding an autometer temp gauge. If it is feeding the 55 Pontiac gauge it is most likely reading wrong.
