Need more info!! What emissions , if any are you running? If none , then you need one hose from PCV valve to big port on carb, one hose from ported vacuum to distributor advance. If th350 you need one hose ( METAL with 2 inches rubber on each end ) to transmission off a full time manifold port. If you have power brakes then one off back of carb threaded to a metal hose to just near the booster , then rubber from that line to booster.
Of course if you have some emissions stuff, its different. Please let us know more, maybe a pic. I looked in your profile for details ,like make and model, but you never filled it out. /forums/images/graemlins/frown.gif
