That larger black hose coming off of the right side, rear area of the carb is usually for a PVC setup or valve cover brearther - something like that. The full time vacuum source you should hook to your distributor is under the front bowl, coming out at an angle and currently capped.
Not completely sure but I think the upper port on the right front side of the carburetor and fuel bowl is a ported vacuum source. You can check it with the engine at hot idle and see if it reads the same as your manifold vacuum. I doubt that it does and I would not use that for the distributor.
Hope this helps a little
