Steve;;    Thank You for returning the email.  Think I'll go with Mark's valve, if that is not good will try your restrictor.   Many Thanks and Merry Christmas!!!   God Bless    Eddie

Let me ask you guys I am having idle problems too. I am running a 292 with g heads and a 3x2 offy with holly 94s. everything else stock idle it tends to idle fine in park but when coming to a stop it stumbles a bit. I have been chasing bogeymen like the PV and vapor lock on the fuel line. Do you think it could be the PCV? The pcv does rattle like a machine gun so i know it is working maybe too much. It might be a good quick fix to try a smaller valve I had never thought about that direction.

I've been away from my computer Eddie and overlooked your note.....

I used the PCV for a '64 292 cid truck and it bled way too much air into the intake. The engine acted like it would run on the PCV air alone. Rather than hunt down another, I orficed the line down to a better match.

Mark's choice of a smaller valve is probably the right way to go - but the orfice will work too.

Hey Eddie! I started with the same as you and found it passed too much air.Wouldn't idle right.I went to a 78 4 cylinder Fairmont/Zephyr PCV and it was just about right.You can try restricting the one you have now and see how that works.Trial and error.

  

Hey Steve,,    I know you did a lot of research on what PVC vale to run on your rig.  Have a little trouble getting idle right.  Believe the PVC valve is not right.  Running 4177 Holley, right now running 67 primary jets will go back to 71s seemed to be better, also using secondarys to control idle.  331 stroker, John's heads, Engle Cam #EP-20-Cam lift 321--duration 231--  lobe centers 110.   Blue Thrunder.   Pvc valve that I'm using is for a 289 Mustang. Maybe too big??     Thanks for all the help thru the years.   Still the Best site!!!    God Bless    Eddie
