How is your PCV routed now? There are plugs in most of 4 barrel intakes I've seen that you could route your PCV to. The part that is harder to come by is the valley pan connection.
Some Y Blockers add a spacer (drilled and tapped) under the Carb with the PCV connection pointed towards the back of the engine. Very similar to how the 70ish EGR valves were installed back in the day.
Everything is exactly as it was when it left the assembly line.
I have the pvc valve screwed into the 2V manifold just forward of the carb, a rubber hose connects it to the hardline, a second rubber hose connects the hardline to the fitting at the rear of the valley pan.
On the 50s era 4V manifolds I do not see the hole for the pcv valve in the manifold. I suppose that I could drill and tap the hole myself, Im guessing that it just goes into the plenum. Or, I could run the pcv valve into a fitting on the carb spacer.
I like the oem setup, its clean, uncluttered, and looks like it belongs there.
Another question: I see finned valley pans for sale, but not with the oil fill or fitting for the pcv.
You'd have to Have a Valve cover that would allow you to pour oil into engines with the aluminum valley pans. That's also where the air intake would be for the PCV. Or no PCV and just the slobber tube (aka Draft Tube) on the Driver's side of the engine. Later blocks didn't even have this ability because they didn't machine the blocks for it.
If you go 4 Barrel many of them have a port on the Carb for PCV.
I'm right in the tail end of doing this mod on my 64 F250. I mounted an Autolite 4100 on top of an old 60's vintage small block Ford aluminum spacer plate that has the vacuum port out the back on a 57 Thunderbird ECZ-9425-B intake. I'm reusing the stock 64 pcv valve and 3/8ths heater hose to hook in the valve. The hose will fit over the threaded portion of the pcv valve and fits to the spacer via the hose. I also rotated the valley pan fitting away from the distro for room. The unthreaded part of the pcv valve will also be fitted with the heater hose and go to the valley pan fitting.
Right now, I'm trying to figure out how to hook up the hot choke tubing to the intake manifold.
