Just to throw another log on the fire...
I now run a 160 T'Stat (with a few other additions to the cooling
system) and she never gets hotter than 167. 182 with the A/C on in rush
hour traffic.

I really don't want to argue about this but a thought crossed my mind
and I thought I would throw it out there. Suppose your cooling system
were in good enough shape to be able to limit the engine temps to 15
degrees hotter than when the thermostat opens fully (sounds reasonable).
Now lets say you compared running a 160 degree stat to a 195 (stock)
stat in that same engine/cooling system. With the 160, your engine temp
max becomes 175 and w/the 195 stat, the engine temp max becomes 210.
Couldn't you say that this limited the maximum engine coolant temp?
I believe I thought of this because its what happened in my case. Prior
to the 180 stat, I had engine temps that reached 210 degrees (100 degree
ambient, sitting in traffic). Now it never gets over about 195.
Comments?
