I just came back from a short test drive and the problem persists -- 5/8" heater hose gets hot, but 3/4" hose to radiator stays cool. No flow through the heater core equals no heat from the vents. I suppose there could be air trapped in the heater core and if so, I hope it will work its way out now that there's a hole in the t-stat.
It's just very frustrating because it has never happened before, and I can't seem to figure it out.

Any Chance there chould be a block in the heater core?
