I connect mine to the vacuum port on my carburetor.

If you connect it to the port on the metering block you will not get any vacuum until the throttle blades open (this is called ported vacuum) If you connect it to a nipple in the base plate of the carb you will get full manifold vacuum all of the time.

I connect it where my pcv valve goes on the front of my edelbrock carb. Hopefully that is the right spot for a good reading?

On my 70 LT1, I tapped a couple of spots on my brake booster aluminum fitting.
