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

Riz - The troubles we were dealing with (downsizing the PCV) are a slightly different circumstance, my engine was acting like it had a big vacuum leak and the idle speed running high. After running out of places to look for a leak - I disconnected the PCV line and plugged it (both ways) and the "runaway" stopped.  So I got a piece of tubing and throttled the hose which helped a lot.

If your outfit stumbles when shifted into "drive" - it may have too little initial spark advance. Try raising the initial advance to something 10° or higher and see what the results are (at idle transfer). You may need to re-curve your distributor a bit so that you can have more initial advance - and then limit it to less on the top end. Because the two-barrels probably don't have a "ported vacuum" arrangement - you will most likely be needing to run "live" manifold vacuum to the can on the distributor. Because it may have too much travel - "adds" too much to the total when engaged - you may have to limit it as well after raising the initial static.
