Jerry,

Thanks for your response. I wish I could answer your technical questions but I simply can't. I'm very ignorant on this subject. I can tell you the engine runs pretty cool (195-200) until you turn the a/c on when it's hot and humid outside. The temp then starts to creep up to the 220-230 range.

Yesterday we had to use the street rod ('40 Chevy Sedan) to chauffeur a bride and groom in a wedding party. We had the a/c on and the car spit through the stacks 30-40 times during the 2 mile trip and then I had trouble with the car idling after the engine started to heat up. It was actually running very good before yesterday. But I think you're right, the water hoses need to be bigger. I had no heating problems at all before installing the Hilborn injection. And the tuner warned me that we might have to go to bigger bungs and hoses. I can see how this might confuse the ECU. I just know so little about this. I really need an expert to take the ball and run with it.
