Where does PVC valve plug into a Holley 600cfm carb?

The PVC (Positive Crankcase Ventilation) valve typically plugs into the vacuum port on the Holley 600 cfm carburetor. This port is usually located on the front or side of the carburetor body and is designed to provide a source of manifold vacuum to the PVC system. Properly connecting the PVC valve helps to manage crankcase pressure and reduce emissions by allowing fresh air into the engine while expelling harmful gases.
