Sweating Throttle Body
I got the 327 built and the TBI modded as far as I could go. Ultimate TBI+ boring out to run the 52mm TPI plates.
After idling for 2-3 minutes after startup the TBI is cold enough to have just come out of the freezer as well as forming condensation. I know that has a lot to do with humidity, but does this happen to anyone else? I've never noticed it until this point.
I understand the principal of a gas moving from high to low pressure will drop in temperature(Air Conditioning). Should this lead me to believe that I have good vacuum at idle and could have gone with a larger cam?

Re: Sweating Throttle Body
On truck BBC TBI uses a heated Q-Jet to TB cast iron adapter plate with coolant passages for quicker heat equalization. I have seen carbs ice-up, but since I live in warmer clement I do not see this anymore.
