I am in the final stages of my '73 351W into the '68 fastback. However, I seem to be lacking the proper resources to determine how to hook up all of the vacuum lines. When I originally purchased the '73 block, it had a number of vacuum "trees" screwed into the manifold. Upon installing a new edelbrock manifold and carb, however, I have plugged all of these holes to do away with the EGR system.
I called a couple of Mustang shops in the area today, but received conflicting info. On the edelbrock 1406 carb, there are two vacuum fittings. The first is a ported vacuum. The second is a full-time vacuum. Should I run the vacuum line from my single vacuum advance distributor to the ported fitting or the full-time fitting on the carb? Similarly, what should I do with the line from my power booster? Also, do I need any vacuum fittings for my manifold, or can I get away with just the carb? Any advice, websites, or pictures would be greatly appreciated. The car has power steering, brakes, and a five speed.

The vacuum advance goes to the ported fitting on the carb. I would run the power booster to a vacuum fitting on the rear of the intake manifold. The shorter the hose the neater the installation, IMHO.

Use the hole in the back of the carb for the PCV valve. You'll need a nipple.

Generally, you'll use the ported vacuum source for the vacuum advance. However, if you find the car runs better on the other port, then by all means use it.
