Vacuum Fitting On Intake Manifold
On a 1969 aluminum intake manifold 427, 390 hp their is a vacuum fitting that sits on top of the manifold between the rear of the carb and the distributor,it points to the right rear on the manifold at a three degee angle. Where does the vacuun hose go???

What you are describing sounds like a “vacuum fitting’s they range from one port to several. I am not all that familiar with a 427 (you are a lucky man) and depending on the options your car has this can be the vacuum source for A/T Modulator, power brake booster (either from back of the carburetor or here depending on the carburetor) and as Alan said the vacuum system that supports your wiper door and head lights. If you have only one port I would say it’s the wiper door and head lights. If you do a search on some of the vendor’s online catalogs for vacuum port or fitting it may give you an idea.

If you have power brakes, vacuum is provided by a fitting in the rear carburetor base.
