COOLING system:
The engine must have a 195 degree thermostat
195 degree high flow thermostat- Stewart Components has the best quality thermostats part # 306
These are manufactured by Robert Shaw and modified by Stewart. They feature a balanced sleeve design and are designed for high flow, high RPM applications. They work! Road course tested.
A very normal operating temp is 195-215.
220 is warm
230 is HOT
240 is very hot

Use a mixture of 40% coolant/60%distilled water and a bottle of coolant conditioner

Beware of high under-hood temperatures. Measure it! Lowering the minimum operating temperature of the coolant to 180 or 160 degrees does not correct this problem. Measure the temp at the base of the carb on intake manifold. It should be the very close to the water temperature. Lean engines and or improperly timed engines create lots of under the hood heat. Power steering pumps create heat so a cooler should be installed.
