There are three vacuum hookups on my carb: timed spark, manifold, and power brake. My MSD distributor has vac advance so that hooks up to the timing vac. Where do I connect the manifold hookup on the Air Gap intake manifold? Also, are you guys using power brake vac or should I just cap it off on the carb? I don't think my master brake cylinder is designed to work with vacuum boost. I don't see any way of hooking up a vac line to the brake master cylinder..
