Hello, what is the correct way to connect vacuum to a 283 distributor? The vehicle is a 58 Spartan with a 283, with vacuum for the hydrovac coming from the manifold. The former owner had "t-ed" into the hydrovac line to gain vac for the distributor, but I'm not sure if that was the original setup. Would this compromise the available vacuum for the distributor advance? Thanks for any insight that you may have.
