I would run a 180 degree Robert Shaw brand. They flow better and work very well at controlling temps without the fluctautions of standard poppit styles. If you cannot find Robert Shaw brand I believe they are also sold under the Mr. Gasket brand name. They look a little different and open in a screw motion.

'stat sets the minimum temp, not the maximum. The max depends on the BTU output of the engine vs. the BTU removal of the cooling system. The cooling system includes the coolant, radiator, fan, shroud (amazing how much difference a good shround properly installed makes), that sort of thing. If the engine puts out as much or more than the cooling system can remove, the stat temp won't matter a lot. Actually, unless there are problems with the engine, hotter is better, more effecient. Too cool means less power put out. So don't try to run it TOO cool. I'd never run cooler than a 180 stat - that's the coldest i'd ever go. I prefer to run warmer, but also go by the manufacturer's specs, too.

The temperature rating of a thermostat is where the thermostat just starts to crack open. It takes additional heat to open it fully. I found on both of my AMCs by experimenting with a number of brands and temperature ratings of thermostats that they consistently run 15 degrees hotter than any thermostat I install. From that anecdotal evidence, I conclude that the thermostats I have tried cracked open at the rated temperature and were fully open 15 degrees higher.
