Hope you get it resolved. For me, I have to tell you that you are the first guy that I have heard that has a lean six pack. Most everyone I have heard of or seen has always been stink rich. That lean stench smell I describe - I usually smell it behind old school buses. Why - don't know.

That lean stench smell I describe - I usually smell it behind old school buses. Why - don't know. Well remember, it's lean because they didn't drill out the idle restrictor passages! I'll see what happens when I get a correct metering block in there. With 2 1/2 turns out to get a 15:1 idle, I assume with a properly working metering block I should be able to now set it where I want.

I would go for that, expect I want to keep the stock look. I know I'm leaving a lot of horsepower on the table by a) having the six pack in the first place, and b) not setting it up optimally, but it's the novelty I'm going for. Once I miss the extra horsepower of my 2X4 setup, (and I do already, just not enough yet), I'll go back to that. But for now, it's just cool having an air cleaner that reads... "HEMI Six Barrel"

Are you going to set up the carbs properly or just wing it and then ask questions? Did you know that Tom Hoover spoke very highly of a six pak on a hemi as the fuel distribution was wayyyy much better than the 2x4 set up? I thinks it's humorous with all the talk that a few ponies were left on the table with the +6 vs 2-4s or a big fat 4bbl when a drag race would confirm that six paks rule!.

I thinks it's humorous with all the talk that a few ponies were left on the table with the +6 vs 2-4s or a big fat 4bbl when a drag race would confirm that six paks rule!. No, I did my research first, installed them following some specific instructions I got here on the board, and now am asking questions for the small issues I'm having problems with. That was one of the reasons I did it, was talking to Tom Hoover about it a few years ago at MATS. But first of all, that was a 426 he was talking about, not a 540. Then there is the fact that at 4bbl ratings, the six pack flows 935 cfm, where the two Edelbrocks I have flow 1300. Then there is the dual plane design of the 6 pak manifold as compared to the single plane Stage V dual 4 I use, which dyno'd by FHO produced 40 more HP than a stock manifold. And yes, setting up a set of drag 6 pak carbs with all 500 CFM carbs may put it back in the range of a single or two 4's, but probably not with that manifold. So this really is in no way and apples to apples comparison. So yes, it is down on power, and would lose miserably on the track to my other setup.

Ok, the conclusion to all this. Got the new metering block from Holley, same result. Probably my fault, but I reminded them, (may not have told them in the first place, thought I did), that I'm dealing with a 540, and they said, Oh, in that case there is nothing we can do for you. This is designed for a 440, and will supply it well, but we can't do or say anything about a larger displacement engine.
Called ProMax, and they said "Yep, that is what our metering blocks are designed for." He also said the six pack metering block is an odd duck, in that it doesn't have an idle restrictor passage in the usual place, which started all this.
So I live with it, or get a Promax block, as Ricky suggested.
All I wanted to do was clean up a stinky idle. I'll live with it for now...

how big is the cam and what is the LSA ? if it has alot of overlap you might be stuck with a stinky idle...
also you have three carb to adjust idle mix on?? can you richen the outboard carbs up a bit and get the center carb a little more in line with traditional settings??

But I will let you know.

If you hate the stinky smell switch to 101 low lead AV gas,you'll love it then !! Is that a sarcastic "you'll love it"? Besides with what I imagine to be $7-10 / gallon prices, I'm not sure about that!

I have it farther down, in the 14+ range, just turns the screws farther out.
I'm just going to live with it. There are other things that need attention, this is just more of a nuisance than anything else.
I didn't expect it to take this much time and energy, but since it is what it is and doesn't harm anything, it's good enough. If you have a large overlap cam you should be focusing on idle quality, not what an O2 meter is reading. It simply does not read right. If the O2 meter is reading 15:1 the the combustion charge AF ratio could still be far too rich. Some have reported as high as 18:1 meter reading at best idle quality w a big cam

Not sarcasm,fact.All I've ever ran in my sixpack Superbird and wagon since 1992,airport is 10 mi over the mountain,$4.35 gal. Do you know about the Federal law restricting using leaded fuel of any type on any public U.S. roads, freeways or highways in all of the U.S.? If not be aware of it, it carries a $10,000 for the first offence I can tell you that every law enforcement agency in California that I've talk to or heard about are aware of it and they know the local courts get to keep all of the fine money from that citation I was warned by a San Bernardino County sheriff about that back n the 1990s when he saw one of my old race cars with current tags at the old LACR race track, he assumed I drove it on the street regularly, which I hadn't done in his presents at that time, he was a drag racer also The smell gives it away
Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
