Hi all. Im not sure if Im even on the right forum, but since I have me II, and you guyz are the most helpful: I have an Edelbrock 1406, mech secondaries, on a mildly built 351W. and currently I have the big Vacuum port tied to the PCV valve. It has (so far) made a really good vacuum in the crank case, but Im wondering what it will be screwin up in the future. I have the carb (sorta) tuned for the extra air getting in, but its not a really good tune, so there is the "lean" issue..... So, what is every issue you all can think of that is gonna happen runnin my car this way?? Thanx guyz, Jon.
