On a 1969 350/350, the normal operating temperature is around 210 degrees. On a hot day, hard driving or prolonged idling on a hot day will produce a gauge reading around the 230 degree mark. When the gauge reaches 250 degrees, stop engine and determine cause of overheating or reduce speed permitting engine to cool. Thats how mine ran when I bought it. New.

I assume this was designed by GM to help with emissions. I now run mine with a 180 degree thermostat.
