so if I install a pcv like the ac one can I block off the road draft tube on the drivers side of the block???

All you had to do was blow into the threaded end.  PCV's are check valves in one direction, so you don't blow backfire into your crankcase.

The one you bought can be used if you screw it into a 1" carburetor spacer.
You cannot screw it into your valley pan or block.

See previous posts.

I wouldn't use it at all if it doesn't work as needed.

I received my NAPA Pcv valve today. Tried it out on a car here in the shop and it works opposite of the way I need it. I guess I'll plumb it in for now and keep looking for one that works the right way.

I did some more research on my NAPA pcv# CRB29255. Fits 63 Tbird & Galaxies 390 engine. Also fits 62 Galaxie with a 292. That must be the pcv valve shown in the epay ad for the part that installs in the valley pan (early Calif. emissions?). Shouldn't cost but a few bucks (I'm lucky, get %10 over cost at NAPA). If it doesn't work, I'll check out the Corvette site mentioned.

Look for a PCV valve for an engine around 300 cubic inches.

I saw one at my NAPA store (for a 283 BelAir) and found it is BLOCKED when you blow in the threaded end.  These valves have no arrow or other indicator as to direction of flow.  You have to test each one.

There are lots of pcv valves that can be used, including the "double hose ends" if you want to do your own modification.  Some have an ell at one end, which helps too.

If you have a carb spacer, you can tap the hole and screw a modern PCV into it (available everywhere for three bucks).

I went to NAPA online, put in 63 Chevy BelAir 409 and came up with part #CRB29255. Looks pretty close to the AC part.

I'm going to give that one a try.

I have checked several parts stores and cannot find the AC PCV valve pictured, anyone know of a source or different brand and part number?

You want that AC type part that Dutchy has used in his post.

The '64 Ford truck part has flow "checked " from the threaded end and throttled from the "hose" end.

The AC part has flow throttled from the threaded end and "checked" from the hose end.

The check valve prevents a backfire from blowing back into the valley.
