Hooking up a Q jet..??
well kinda sounds like a stupid question... but i got most of it figured out.. im swapping a holley double pumper to a Q jet rochester.. the fuel line is simple.. the brake booster is easy also.. but for my vacum advance theres to possible connetions.. one at the base of the carb.. and another about 2 inchs above it.. wut would be a better vacum source? also theres one more port or wutever its called.. at the very front bottom at the bas in the center of the carb.. its a bigger connection.. is this for PCV ?? also theres one above it.. but it was not used cuz it has a rubber fitting holding it closed.. my PCV right now is directly to the manifold on my edelbrock performer.. i just not sure wut to do with the 2 choices for vacum.. and just close off the others i don't use?? thanx for the help on a dum quesiont.. hope u can understand wut im asking.. kinda typed this fast.. sorry guys.. thanx!
