I had a 56 schoolbus/camper with a 396 in it that did the same thing. I
replaced the thermostat, gauge, new flex fan and eventually re-cored the
radiator, with no results. finally said the heck with it and ignored the
gauge. I sold the bus and a few years later the guy pulled the heads. he
said the head gasket had rusted all of the restricting holes in the water
jacket and that he figures it created a low flow situation aroud where the
sensor was located. it didn't affect the engine at all and it never ran hot
again.
