Picture/Schematic of 1965 427 FE PCV Plumbing?

[ACHiPo]

Can someone direct me to pictures of PCV fittings and plumbing for a 1965 FE?  I will need a closed PCV system for my Cobra replica to qualify as a 1965 SB100 registration in California. While I could rig something up to pass, I 'd like it to look stock.  From what I've found on line I need a hose from one valve cover to the filtered portion of the air cleaner, and a hose from the PCV in the other valve cover connected to the base of the carburetor. I've also found a bunch of other configurations, including going directly into the intake.  I've got a Blue Thunder dual plane intake and Holley 750 vacuum secondary carb.

Thanks in advance.

I found this assembly drawing for 361 - 391 closed PCV system on trucks, but not sure if it's applicable or how it would look different on a 427?


For some reason I can't attach the picture.  Here's the link:

This is in a Cobra, correct? I don't think I've ever seen anyone put a closed element air cleaner on a Cobra. Shelby's that had the open element air cleaners ran a PCV to a rear port on the intake. I believe it was the one directly below the rear carb on 2x4 intakes. I'm not sure about 1x4 intakes, but I think they were ran to the port that fed #8 cylinder. I'd think that would satisfy their requirements of a "closed" system.

On my 64 there is a PCV valve in a bracket thats bolted to
the two bolts that hold the throtlle linkage. A  hose from one
end of the valve to a spacer under the carb and a hose from the
other end of the valve to the port where the
road draft tube used to be and the filler cap on the intake is vented

On a 66 Engine i have there is a PCV Valve in one cap in the valvecover
with a hose to a port in the intake runner to nr 4 cyl and a hose from the
aircleaner to the cap in the other valvecover . I thought 66 was the first year for
closed crankcase vetilation in California

This is in a Cobra, and I haven't seen it either, but the Powers That Be say I need a closed PCV system to be consistent with 1965 emissions standards.  I met with my engine builder yesterday and he said he can get me set up, but I'll need to modify the air cleaner.

That's the sketch I'm looking for.  Thanks!  The current interpretation is that 66 required closed PCV, smog pump, etc.  1965 and before was just closed PCV so I take it.

Just my opinion, but a closed element air cleaner would look WAY out of place on a Cobra, IF you can even fit one on it. Space is pretty tight under those hoods. I don't think you'll have room for carb spacers either, so I still think I'd look at running it to the intake.

This style is a bit overcomplicated, but I think you'll get the idea of how it can be run to the intake.

On the Galaxie now i have a Cobra repro aircleaner there was a "dimple"
pressed in the a/c bottom that i drilled a hole in. I glued in a tube there
a hose from that to driverside valvcover a PCV on the pass.valvecover to the
big vaccum tube in rear of the carb

I grew up in SoCal and had Mustangs '65-'67.  '65 had a PCV system only, and starting in '66 they started putting the Thermactor (air pump) system on as well.  So for '65 PCV only should be correct.

That would work good, Heo. And you could still use a filter on it to help keep the oil mist down, as long as it's secured good so nothing got sucked into the engine.

Have you considered using a puke tank? They were installed on Cobras and used for the PCV. You'd just have to route a hose to the bottom of an air cleaner like above, and it would still look pretty accurate. The puke tank as installed in 427 Cobras used a road draft down tube coming off one end of the tank, and the puke tank was connected to both the engine and the 4 speed toploader.

Interesting bit of history about 427 Cobras... only a few of them actually had a 427. Most had a 428 because the 428 was cheaper. And most original 427 Cobras didn't come with side pipes. What people see when they hear about a 427 Cobra, is the 427 Cobra S/C (Semi-Comp) of which only a small handful were made. These had the 427, as they had been intended for racing but Shelby had a hard time selling his full-comp Cobras.

yes Doug Thats just a late night Quick fix. welded a washer on a 13 mm piece of tube
and glued it to the aircleaner with some TA-31 and a hoseclamp on the outside holding
the hose so no risk the Engine will eat it
The Engine is on its way out again soon and the frontclip of so i can restore the engine bay
Im`going to press a flange on a tube and solder it to the air cleaner then bend up some
Stainless tube with hose just at the ends and get some better filler caps.
And reroute the line from PCV valve to the intake where there is a 3way fitting for vaccum
modulator, brake boster and one plugged now

There is a pic of the set up in a 67 motor assembly manual.

Thanks guys.  Lots to digest!
