Is my engine low on vacuum????????????? Help?????

Hee-hee.....#6 is to be expected from your combination LOL. Good deal on that part.

I suspect that the increased vacuum is just from the increased RPM's with the added timing. If you put the timing back and turned the idle screw up, then I bet you would have the same vacuum.

Yep, probably time to do a very different PCV. Do you have the PN that was given to you? The stockish Mopar PCV's are wide open to the higher cruise flow opening at your level of idle vacuum and typically putting too much air into the intake. It makes the vacuum low and messes up adjustments.

Try a Mopar Performance PCV valve # 4343581. Also the Fram FV191 works for your size cam but has a large base. The objective is to get the right PCV that will close down to the low idle air flow level when you have idle vacuum levels.

Do that first and see where your vacuum is. It is important to get the PCV working right before other tuning adjustments.

As for the secondary transition slots, you may have a to close the secondaries a bit to start; that is what we had to do with both a 675 and a 600 cfm Holley on our 340 engine. The point is to get the secondary transition slots completely out of the picture, so that they are not adding any fuel to the intake at idle. Then the primary idle and mixture screws will have complete command over over idle operation, and the primary transition slots will control the part throttle, off-idle response, as they should.

And as for your use, I personally would not go too aggressive on the ignition timing. The higher compression ratio that you have makes up for a lot of what strongly advance timing does for a lower compression engine, and you are not after every fraction of a second on the track.

The cam timing just has to be assumed unless you want to go back into the front of the engine. It can't be far off, if at all, with the TQ and HP numbers that you list.
