IT's skipping some of my post so I don't know if I am repeating myself but..........
These are pictures of my metering block and bowl so hopefully someone can tell me if they are 340 or 440 pieces.

Well I modified my distributor today and put the 64 jets back in and returned it to my base settings. I regained control of my idle and it performs extremely well again with the exception that the surge it back/still there. Starts fine, hot started fine, accelerates cleaning and smoothly, idles well down to 600 or so if I wanted. Would have no need to cure anything if it wasn't for the surge. I ordered a set of 66s today that I will install tomorrow, it will be too rich I believe but I can at least see if it solves the surge and go from there.
What determines if a picture post or if it is an attachment? I posted them all the same way. Maybe it's the text???

The 6610 block is 340 also as is the bowl which incidentally if that's the way you took it off ,float level is way to high.

Thank you, what problems will the 340 block and bowl on a 440 center cause? I set the float level at the bottom of the window with sight glass per Tom's instructions, I think Dayclona's call for halfway up the glass. It isn't loading up and I cant tell that I am getting bleed over in the carb. Any suggestion on the surge other than going to 66s? Another question, should the secondaries hold vacuum when pulled in the port? It activates but doesn't hold, the pods will hold if I have them in my hand and push the diaphram in and hold my finger over the hole. When I have it mounted to the carb it doesn't hold and I hear it bleeding off inside. I double checked a 440 set up I have and it is the same. AND they definitely seem to be fully engaging when I am on it.

Almost any vacuum leak will cause a problem.

right, while I'm checking in mid-stream, just wondering if sorting the carbs is chasing a symptom rather than the cause.
I noticed op's other post of the sooted-up/white insulator plugs.
Got me to thinking that a vacuum leak down-stream of the carbs may need investigated. i.e. a split booster diaphragm that opens up under high vacuum only.

There is a air bleed inside the venturi behind the vacuum diaphragm,if you look down inside you will see a small hole cover it with you finger and the diaphragm tube at the same time,it should hold vacuum.On the float level,you will notice the sight plug is higher on the center carb,you can go higher on the ends but will probably have a problem if you go much higher on the center.Just finished this set,sight plug location is very easy to see.
Date code on bowl is 82.
Next post has air bleed location.
I'll cover the bleeds today and make sure the pod to body seal is holding later. Using the sight glass, I set it to just be visible, afterwardds when I removed the sight glass to put the plug back in it didn't dump a lot of fuel like one that is set high either. The base float set up I have always heard and used on a center pivot you set the top of the float parallel to the top of the bowl and then adjust on the car running. In the picture my bowl isn't close to parallel.
I will definitely give you this, mine don't look nearly that good, not to get your trade secret but do you recoat the carbs or is that some brand of carb paint?

Set the fuel level with the engine running, for starters bring the fuel level up to the bottom of the site plug hole, I too like to use the clear site plugs, as I bring the center carb fuel height up to the center of the window, for street use just at the bottom of the site plug is fine, if your going to throw the car around a road course/track event, then that's when I bring the fuel level up to the middle of the site plug on all 3 carbs"new" Holley clear site plugs suck!, as you found out earlier, they just dissolve with fuel and soften up, the Moroso clear site plugs I have heard from another member are much better if you want to keep them in, all my six pack cars run clear site plugs, fortunately I bought a number of them years ago, but a recent set (Holley) I bought for a 4bbl application lasted like 1 day before the suckers snapped off!
Anyway here's a closer pic of the air bleeds mentioned earlier (not a six pack carb, but still a Holley for reference)

Yep, I found the air bleed and had a slight leak in the front one, pulled the pod off and the o-ring appeared pinched, I replaced it and then they both had when I put vacuum to them. It wasn't enough of a leak to keep it from working and I cant image it would have caused a running issue since the air bleed is a built in leak in that circuit. I replaced the jets with 66s today and it pretty much cured the surge, I think I might feel it slightly but I may also be convincing myself of that. It doesn't appear to be running too rich from the plug readings I am pulled and from what my eyes and noise tell me, so that much is good. It was hard to start after the replacement and ran like cr@p until it was warm, doesn't stall but idled a 12-1300 RPMs, the hot restarts are not terrible but definitely spins longer than normal before it fires. I am going try to adjust everything out tomorrow if I can with the 66s. I'd rather it run a little rich and not worry about leaning the engine out on my trip. The hot start I can live with but the ragged running on cold start up might make me go back to 64s and live with the surge. Dayclona, does the float level like high to you in the above pictures? I have more on this but I will hold it until you add your opinion, so I don't taint your thinking.
