rig it like any of the post '62 inline chevys. For a 235 with say a '55 nonvented valve cover use the filtered oil fill cap for fresh filtered air intake and suck it out of the valve cover (maybe a welded-on 3/4" nipple and hose with a pcv valve plumbed to the intake manifold. make sure the pcv valve allows flow toward the intake-they make them to flow both ways-pay attention to any flow arrows. The system will make most any older fumer fumeless, and the cab atomosphere more pleasant on hot days.
