In my car, which granted is a 1953 327 with a 4 barrel, coming right near there is the hard vacuum line that goes to the vacuum advance on the distributor. The line runs over the top of the engine. Maybe that? The other would be a vacuum line to the windshield washers, typically involving a line also to the vacuum side of a dual action fuel pump as sn assist. Also a possibility.
