['68OrangeSunshine]

My '68 C/10 Stepside rolled out of Fremont sometime in early 1968 with a factory L-25 292 L6. Being a California truck with an in-state end user, Felix Chevrolet, it had smog equipment which included a PCV system.
While I ditched the A.I.R. compresser and fittings to the head a year after I bought it, while stationed in North Carolina, I kept the PCV set up.
When I upgraded to an Offenhauser intake, 4 barrel Holley carb*, and Clifford headers, after getting out of the service, I reconfigured the PCV system to the new equipment.
Now the hot gasses exit the top of the rear valve cover thru the PCV Valve into a 3/8'' hose that plugs in front of the carb. A 1'' [~] hose goes into the side grommet on the forward valve cover and connects to an elbow fitting that gets fresh air thru a hole in the bottom of a Moroso air cleaner.
Works fine.

* Holley 390 wore out after 250,000 miles. I replaced it with a 500 CFM Edelbrock 1404 when the original 292 was rebuilt after the first rebuild ran 25 years.
