Are we both talking about a 235 and not an SBC? I know V8's draw vacuum off the rear cylinders but the vacuum port on a 235 is directly below the carb and an open log manifold? A PVC system will draw fresh air into the crankcase from the air cleaner housing but still needs a feed from the crankcase gasses into the intake (vacuum) stream going into the combustion chambers.
