Thanks, I'll try later on the Ebay and other links as I need to and I will ask about flange thickness. Stock 49 is that a truck or a car? The line to the back choke is that T'ed off the front line? You are using water to heat the intake manifold right? If I understand correctly the heat helps atomize the fuel and it is suggested to use water or exhaust heat. When using water does it circulate back?
