It wasn't the best system in cold climates. There was a mesh screen under it and short drives in sub zero would freeze it into a block of ice. Blowby would start oil leaking from all the gaskets and seals.

FORD actually first offered PCV in the 1960 model year, a model year earlier than the CA requirement. As for the 292, it had to comply with differing area emission law(s) so it was fitted with PCV. That is why it is so confusing as the engines were built/calibrated for where the vehicle was to be sold.

Either FORD had to bring the 292 into compliance or was not allowed to sell the 292 equipped vehicle in CA for instance.
Well...

Finally got the cartridges but FIREFOX updated my browser and I cannot communicate with the printer.

As soon as I join the living again, I will show the drawing.

ADDENDUM-

SHELBY COBRA TIGER

Yeah, that is the actual oil/vapor separator and is necessary. It is replaced on a scheduled basis.

Gasket PN- C2OZ 6870-A (FEL-PRO should have it)

Road draft was absolutely used in the 1965 model year. Absolutely.

When and if this all goes togather I have a 66 4 bbl intake that has the provision and the three threaded holes for that PCV system but the larger hole is not drilled so it will have to be machined.

They were delivered different ways. Some had a plug in the hole. Some had nothing but a flat place where it went. Some had the threaded holes for fasteners, but no opening for the gases.

Now we are talking 5.0L EFI correct? Was your 5.0L HO, STD or LT? How far north were you when the system froze?

Now for the earlier road draft design.

Two SBF tubes shown below, one manifold mount and the other rocker cover mount (1965) -

The PCV on the EFI is a pain to get to.
