HI! I have a 1964, 283 that is going in my 51, 3600. I have power brakes in the truck that require a vacuum line and the engine has a PVC valve that also requires a vacuum line. These line are approx 3/8" in diameter. My two barrel carb has a 3/8" fitting in the base, in the back of the carb. The two large vacuum lines seem quite a bit to run into this one fitting. How about suggestions as to how to make this situation work?!
