The is the first time I have ever installed a new quadrajet carb without having an existing set-up around to go by . . . so I am putting the question to the hamb. What are all of these vacum ports for? Specifically I need to hook up the vac. advance on the HEI and the vac. line that runs to the carb. . . but whoever can label them all wins. The prize is the warm fuzy feeling of being cooler than some dope in CA that doesn't know one from the other The first pic is from the passenger side front. The second pic is a view from the drivers side rear.
