"normal" temp is 200, though I don't know anyone that thinks that's really normal. Performance is best at 180. Speaking of which, I have a 180 thermostat, one 14" puller fan in front of radiator, a 16 " pusher fan in front of the engine, and I still get to 200! Well, I DO live in El Paso TX. The temp here is upper 90's to 100's so that's ok I guess...... :sosad:
