I recently installed a valley pan with the provision for a PCV to eliminate the road draft tube on my 272. I have the rubber grommet, PCV and my aftermarket carb has a port for a PCV set up. I've looked everywhere but can't seem to find a PCV hose to complete the installation.

I'm in need of a 3/8" ID hose with a 90° bend. The legs of the hose need to be around 8" so I can cut them to the correct sizes. Anybody done this? Got a part number? I can't use a straight hose as it kinks when I try to make the 90° bend from the PCV to the carb.

 

I would just buy a 90 degree plastic elbow and use two hoses? Should be able to find something like that in the "Help" aisle at any parts store

 

If there was a factory part or assembly of parts to provide a PCV system for the Y-block, it would be in the last year(s) of the use of that engine, 1963-ish. I think PCV valves and plumbing were mandated around that time, and the Y-block was relegated to trucks.
If you don't care about that, you can use just about any fuel-proof hose to route the blowby gases to the carburetor.
I assume you will be mounting vented caps of some sort on both rocker arm covers. That should allow the flow of fumes from the rocker arm area, to the crankcase to the valley above the cam and lifters. It might be more effective to mount the PCV on one rocker arm cover, whild the inlet for airflow would be on the other. That would tend to keep the deposits in the rocker area somewhat manageable and closer to being equally ventilated. You would not then need a second vented inlet, and would be closer to following the general idea of PCV flow as installed on other FoMoCo products.
I think having a inlet side and an outlet side would provide more even airflow through the rocker areas and sump.

The easiest way out of it is to get a ninety-degree elbow and plumb it into PCV (VACUUM - OIL RATED) bulk hose.

If you use the system on the rocker covers, you will need baffling under the fill cap (fresh air inlet breather) and PCV valve positions.

You can also go into any large parts jobber and they will usually have hoses on a rack and you can pick and choose from there. You may have to modify.
