what? Ducky, you plugged your steam port line? You don't like your new V8?

The water line going through the throttle body, one side comes from the steam crossover line on top of the head, the other end went into a water line fitting on the radiator. You can bypass the throttle body with a piece of hose going directly from the steam line coming off of the head and going straight to the radiator or a fitting in the coolant stream somewhere other than an overflow bottle.
