I am putting together a 396 running a weiand high rise manifold and a holly 780. There is no port on the front of the carb or front of the manifold to connect the pcv hose. There is a large port on the rear of the carb base which I have the power brakes connected to. The pcv is suppose to be connected to manifold vacumn. Should I share it with the power brakes, go to the base of the air cleaner or pull the manifold and drill and tap a fitting.
