May I jump in and ask a very related question? I've plumbed water heat to my Offenhauser intake, which has a 500 cfm Edelbrock carburetor. I put "shut off" valves on the supply and return lines, just in case I ever wanted to shut the water supply off.
As you can see by my profile I live in Georgia and the summers can be quite toasty. Still for the last year and a half since I built my engine I have always kept the hot water taps open and flowing to the bottom of the intake. The flow is non-stop. Is it possible to overheat the charge? If so, what problems could you run into?
