273 overheating after new timing chain set and waterpump

Still curious what "real hot" equals in degrees? I run a $9 amazon reman here in Florida and during the summer 95+ degrees, headers, stopped at a light pavement is proly 120 and with a 195 thermo my sun gauge cycles between 190-200, you could set you watch by it!

Last fall? what 60 degrees? and your comparing that to the summer heat?

"I had a problem last fall with overheating so I installed a new thermostat and it ran nice and cool again, under half on the temp gauge even in hot weather in heavy traffic."
