Listers,
Some cooling inefficiencies might be from the body design. I read an
article years ago about engine cooling for a Morgan where someone
measured the air pressure on either side of the radiator. He found that
so much air was collected by the fender design that under the car became
a high pressure area and that much of the air would go around the grill
because of this rather than through it. Modern cars attempt to create a
low pressure area so air will go through smallish grills. Even with
this Miatas have the same high pressure bounce effect in their cooling
systems.
If that was true of a Morgan the t-series has more of an air gatherer in
its fender design. I don't remember these issues with my B but I do
remember cooling being a big issue with a full fendered '32 Ford.
Anyone ever look at this on a T-series?

How do modern cars regulate their temperature so well?

I think it's more of the difference in radiator and cooling system
efficiency. On older MGs designed for Britians temperate climate the
cooling system is marginal for may areas of the US. Thus the real
opperating temperature is that shown during the cooler days. On real
hot days the engine is actually running warmer than the thermostat is
set for as the radiator can't handle the heat.
With the new cars the radiator and cooling system can handle the heat of
the summer better. Thus there is less fluctation from summer to winter.
