    attaching a vacuum gauge
    « on: May 15, 2014 - 08:58:54 AM »
    Hello

    I bought a vacuum gauge to tune my challenger. It has a 360 with an Edelbrock carburator. I am hooking the vacuum gauge to the small port on the front of the carburator on the drivers side. I believe it's called the manifold port. Is this the correct port to use? or do I need to go directly off the intake?

    Manifold vacuum is fine

    Manifold vacuum is correct, you should see constant higher readings at idle or constant throttle that drops off when you suddenly open the throttle.

    Yes drivers side port or manifold should be the same.  If you put it on the passenger side by accident, you'll know it.  You'll have zero vacuum unless you open the throttle.  That's the vac advance port for the distributor.
