Re: followup - good operating temp and thermostat questions
 
The thermostat when open still meters the flow with a specifically
sized orifice, to about a quarter of the size of the radiator hoses, to
give coolant going through the radiator enough time to cool. Hot Rodders
not running engines controlled by the SMOG nazis, want the maximum
expansion of gases, and will use a metering plate with a 3/4" hole in
place of a thermostat. For this extra horse power, be warned that
running 165 degrees or lower will cause excessive cylinder taper wear.

Re: followup - good operating temp and thermostat questions
 
It is supposed to have a 195 thermostat in it according to my manual so
it runs at 'least' at 195 degrees...

A 50/50 mix of antifreeze and water boils at 265 or more.

210 sounds right to me. That leaves a pile of room before you get close
to the boil over point.

You also need to note that the thermostats are notoriously not
accurate....

Ya that's because they advance the crap out of the timing and run them
lean and mean.

They also rebuild them every 100 miles or less....
