The Stovebolt Site Forums The Parking Lot Big Bolts Original configuration 1967 C50 327

Hideho all,
Anyone have information on the original configuration of valve covers, air cleaner, and hoses on a 1967 327 2bbl? PO was a tractor mechanic and did a bunch of "modifications" over the years, not all of them being successful. I would like to get things back to what they should be. I have a diagram for hose routing on a Caprice , not much help cause it is all different from anything on this truck
Thanks!

http://www.autozone.com/repairguide...AMS/VACUUM-DIAGRAMS/_/P-0900c1528007dbe6 Best I could find! searched for 2 hours! A lot of wiring diagrams,Not much on Vacuum!! Same thing with my T.F. '55 Chevy 2-ton! I bought a Truck Shop Manual,and there was nothing in it for the hydrovac or the 2-speed vacuum plumbing! The "brake" side of the hydrovac was covered,but Not the vacuum routing! The only "problem" I had was when I attached my 2-speed lines.I had them switched. Button "Up" is "Hi","Down" is "Lo". I switched the lines at the diaphragm,and it worked as it should.

Thanks, Thought it was just me....The valve covers have both had half inch copper pipe brazed into a hole cut and hoses routed to the same kind of setup to the underside of the air cleaner housing. Manifold has a plugged rubber tube just to the left side in front of the carb and vacuum hoses...?

If you google "1967 C50 327" and click on images, there are a couple of pictures of 327s and their hose routing. May give you some clues.

So I have figured out that there is no PCV valve in the system...there is one hose run from each valve cover to the underside of the air cleaner housing. It has a breather cap on the oil fill tube up front and a bolt in a rubber hose in the vacuum fitting in the manifold in front of the carb. (2BBL)
Seems like this would just be sucking crankcase gases directly into the carb. How should this be properly set up. I have a replacement OEM air cleaner housing in a box and it has no hols in the bottom for any fittings. What to do?
On a positive note I got the hoses to the bed hydraulics replaced today and she lifted to the sky for the first time in 20 years.....
