I think this is like many of these old Fords I have encountered up here.
These were every day drivers and people did some interesting things to stay warm.
I have a 47 Coupe In the shop now that had four heaters on it, three coolant and one hot air(an under the hood heater core that blows hot air in the cabin).
Is just seems that after a certain point you can't get any more heat out of these old flatheads.
Maybe you don't see the same sort of set up down there in the banana belt.
