Removing the thermostat will more likely make it overhaet faster. The thermostat in addition to controlling the coolant temparature also acts as a flow regulator. Without it, the coolant will flow too fast through the radiator, and will not be able to dissapate the heat effectively. If you do want to try runing without the thermostat, use this old Flathead trick. Install a fender washer with a roughly 1/2" hole. This will help regulate the flow, and prevent overheating.
