When if ever did Studebaker increase engine operating temperature from 160 degrees to 180 degrees? What is best for a V8 , block cast in Dec of 63? This is in my 55 President. Is 180 or 160 best? Any opinions?

Stock thermostat in '55 was 160; later it was 170. I don't think 180 was ever a stock thermostat, but it was available as an optional high temperature unit. 170 thermostats are no longer commonly available however.

My feeling is that if it runs well and doesn't overheat with a 180 degree thermostat, use it - an engine will be more efficient if it is at a higher temperature (within reason, of course.)

I would like to find a 135degree thermostat for my Rockne.

Some manufaturers use different thermostats for different climates.
The ones I've experienced, used higher temp ones for colder climates. I'm not sure why they did that.

To ward off atmospheric heat leeching, I'd bet.
