vacuum gauge
I have located a bolt on top of the intake manifold on the drivers side on my 454.I would like to install a vacuum gauge their.I know i would have to unscrew this bolt and attach some kind of fitting....

Hi,
It is much easier to tap into a existing vacuum line, and install a 3/16" tee or 1/4" tee if the line is a really large one. That way if the line melts, and say you get a large vacuum leak, it will be into a small fitting, not one with a 1/4" connection directly to the intake manifold.
Large vacuum leaks can cause pinging, and engine damage.
So look at the manifold. Look for some black tubing going from it, and one might go towards the distributor, or some other vacuum controls. Cut out about 1/2" of this and take it to the auto parts store. Buy a tee that fits that line, and connect the vacuum gauge there.
