I notice You have Fuel Line in place for the PCV. Do You usually use Fuel Line or PCV Hose or is this just temporary?     

GOOD POINT!

PCV hose has to be vacuum/oil resistant rated. Some hose is rated as both vacuum/pressure. You can buy formed PCV hose with a ninety-degree angle (cut to fit) to lessen the chance of collapse and better appearance.

____________________________

The vacuum inlet on the ECZ-B intake is meant as a vacuum source for a booster/wipers. If used for PCV, the fumes will be limited to NOS 7 & 8 cyls and will cause possible cylinder(s) fouling and the cylinders possibly running lean. You want the PCV fume ingestion to be introduced into the intake carb plenum for equal distribution to all cylinders.



The CASCO kit I showed has a 3/8" plate whereas OEM is 1/4". Instructions say specifically not to use the 55 BIRD base gasket because of the thickness.

There is little choice on the BIRD unless you use the vacuum inlet on the front of the carb plenum on the 55, adapt ingestion to the vacuum fitting on the H4000 carb base on a 56, or drill and tap as shown.

Sorry as I am a detail nut (CDO - correct alphabetical order)

Since  you are going to require a carb adaptor & mods to your "A" manifold, you might want to aquire instead a "B" manifold which will eliminate the carb adaptor & as pointed out also has a vacuum port at the back. And using a carb adaptor can sometimes be less than ideal for performance. The B intake also performs better when the revs are up a bit.. Just a thought or two..

this is just my opinion, but I would leave this as an open PCV system.  That means you use the PCV valve and hook it to vacuum, but that you don't install the hose between the valve cover or oil filler cap and the air cleaner.

Nah, your thinking is good. However, one has to find a quality cap that has an effective filtering media. Most of the junk I have seen recently has that plastic foam insert. IMO, you need to find one that uses a coarse metal media heavier than say an SOS pad. And of course it needs to be serviced on a regular basis.

If the Kit above is used with an Adapter Plate to use the later Carb on an "A" Manifold as well as a Phenolic Spacer(recommended)  the Stock Air Cleaner Clearance on a Sedan is going to be very  close. Either use a "B" Manifold or Tap for a Fitting as Ted suggested close to the Carb Base.

With the kit above (teapot kit)you should not have any hood clearance problems on a sedan.  However, on a Bird it is very tight and clearance should be checked.

I cringe at the thought of violating an origional OEM piece ...
