Has anyone tried a MILODON HIGH FLOW THERMOSTAT 180 DEGREE PART # 16406 ? It is the only one I can find for a 1962 390.[/QUOT



Good to see you're getting the problems squared away.

Before you spend a lot of money on a specialized thermostat, keep in mind that the stock types have been working well in these cars for many years.

Pull the thermostat you're running and test it in a pan of boiling water.
Use a glass candy thermometer and note the temperature when the stat opens.
Both the start of the open and the open all the way.

It would be nice if you had other stats to compare with.
In fact, boiling two or three will tell you a lot about the one you're running provided they are all rated the same temp-wise.
Not a bad way to go if you don't have a candy thermometer.

Candy thermometers are available at cooking stores for not too much $$ and are fairly accurate.

Get your own, don't be stealing Sweetie's....
