I see what Camaro 69 is getting at, and the problem is the newer Holleys don't have a fitting that's sized for the hose you have on the vacuum advance. You'll need to put T in either the vacuum brake booster line, or the PCV valve line to make it work. Once it's hooked to full manifold vacuum you can readjust the distributor to get timing right at idle and it will be fine.
The old Holley on my '71 has both ports, but the new ones on my Austin's tunnel ram only has the metered port, so I set timing with it hooked up, not plugged and then hook it up. If you set your timing with the dist. hooked up, then your's would be fine also.

Ok, so start over. I am apparently missing something in that article.
So, that port on the carburetor is refereed to as ported vacuum?
Then, manifold vacuum refers to the lower port on some older Holley's or making a hole in the manifold, or using an adapter plate with a vacuum port?
Where do you want me to start checking vacuum levels?
Im guessing I need to make some sort of adapter to try testing the pvc port?
That carb is clearly not emissions legal and was not designed to conform to emissions. Therefore, I didn't feel they would porly design a racing carb. It say all over it not for street use, not street legal, racing applications only.
There are not any holes or places for a vacuum line on a victor jr intake. Again it is only for racing applications. I do not want to drill a hole in it, just to test a theory.
"vac can", what? I don't have a vacuum can. There isn't a single stock piece on this truck. I removed tune port fuel injection. Just for info I had the same idle problem with tune port injection, due to the size of the cam. Idle isn't even controlled by vacuum and I had issues with it idling to high.
So, im lost. I have read that article 15 times. I am clearly not understanding something. I am not trying to argue. I really do respect your input. But please start from the beginning.
I just tested the ports on the camaro. Upper port that Holly says to use has 12 lb of vacuum at High Idle while the lower port has 10lb of vacuum.

"Not for street use", that's how a lot of performance parts companies get away with selling their parts without liability. Of course it's going to be used on the street. I think I may have one or two "not for street" parts on my car too.
"Vac can", I was referring to the vacuum advance can on the distributor, Sorry, didn't mean to confuse you there.
