    Ports: 1. intake behind carb (large)
    2. base of carb in back (large)
    3. base of carb in front (small)
    4. front metering block above (mixture?) screw (small)

    Hoses: 1. power brake booster
    2. PCV valve
    3. transmission modulator
    4. vacuum advance

    I could hook it all up, But I would rather put them in the right places, so I am asking.

    ALSO....When timing a motor with a vacuum gauge, where is that connected? I have a Holley 1850-2 if that matters. Thanks in advance for helping the newb.

    Does your intake have a 1/2" plug in it behind the carb if so then you could put a fitting in there preferably one with a couple smaller ports on it and could hook up transmission modulator to it and use it for vacuum gauge.

    large fitting at base back of carb----- pcv valve

    small fitting base of carb front---- ported vacuum advance only gets vacuum after higher than idle rpm. Most people use this one and is how it came from factory

    small fitting above mixture screw ----- full time vacuum advance has full vacuum all the time except at full throttle. People use this to achieve instant advance on distributor some claim it is better this way but you have to set your timing or you will never get the car to idle down. Best to let you research this subject because I dont think I could explain it clear enough

    Oh my, that helps in a million ways! Assembling what has been torn apart and altered by someone else is a challenge for me. That link is GOLDEN!
