[chevy boy II]

i got a 305 in my monte right now i switched the carb over to a holley no more quadrajunk on it... can i get rid of all my vacuum now and just run vacuum to the tranny and brakes of my new carb....

Why would you take off a quadrajet and put a holley on in the first place?
Have you done other significant mods to the engine already??
That quardajet will work excellent up too about 400hp.
Your heater/a/c modes are vacuum operated, the distributor advance needs vacuum, along with the trans modulator and brakes.
