Yes, you may have problem with a stuck thermostat or a missing one. I know 350 is missing one, will remedy that this winter.
As for and abnormally strong water pump, what's your idle speed? If memory serves should be about 425 rpm.

Its not gonna be an abnormally strong pump if its the thermostat, the pump is most likely normal. If my thermostat is stuck or missing, that's why I'm seeing such a large volume of flow through the top of the radiator. The more I think about it the more it makes sense, I nearly forgot these machines had thermostats.
Any downside to leaving it be? I know its not right and I should get it fixed but I don't have the time or shop space to do it currently.
