Dual 4's are more impressive than 3-2's in my book.
I had a T/A setup on my Dart back in the 80's and didn't care for it.
Dual quads on the other hand.. Never had any tuning issues and ran like a scalded dog.

I like the build you're doing. I went a similar route on my build except on a big block. The six pack I'm running has the manifold deep ported and uses the mechanical secondary carbs. They all have accelerator pumps. I don't really like the feel of the vacuum secondary style of carbs, but that's a preference thing. The six pack gives the motor a Dr Jekyle & Mr Hyde type of personality, mild mannered with decent mileage while on the center carb, and brutal power and acceleration when the outboards are tipped in. When the unknowing ask to go for a ride in my car, I innocently lull them into relaxing by driving smooth and normal on the center carb. Right when they are all relaxed and not expecting it, I tip in the outboards, the motor changes personality with a sinister, Mr Hyde-like roar, their legs and arms lock to brace themselves as their eyes get as big as silver dollars. 700 hp will do that too you. As soon as I go back on the center carb, they all seem to have a smile on their face that outlasts the ride home. It's the little things in life that make me smile these days.  When the motor was being dynoed, I had them test it with a big 4 barrel, the six pack was a bit stronger in the mid-range , and the single 4 eeked out a handful more hp at high rpm. For me, my car would be bit less fun to drive and not as street friendly without a six pax on it.

why not go efi with 3 2v throttle bodies? I think I saw that setup somewhere...then youd be the only kid in town with one for sure and all the tuning issues are done by the computer

I have seen some very stout running 6pk cars.  I have seen dyno test on 440 engines where the 6pk made as much power as a single plane with a single carb. Only when it had the dominator did it make a tad more. Ron

It really comes down to personal taste and expectations  IMO people think this is best or worse based on gossip and B.S. Street/Strip wise its hard to top. I`ve run a 6bbl. since 1983, runs with the best of`em. BUT,,,,,, I`m also sure I could go quicker with something else IF I put as much time/money into finding it. How much faster is a new argument

Thanks! There has been some thought put into it for sure. I like the idea of using mechanical secondary's and accelerator pumps on each one. More info please. So far the six pack is winning this debate!

I am hoping to see 600hp out of this motor. Should be fun in a street setup.

I thought about trying a six pack set-up on my FAST duster just for fun. Not sure if it would fit under a stock hood though. My hunch is a ported six pack intake would yield a decent power increase over a ported factory intake but little or nothing over a good 4 bbl single plane intake.

The mechanical six pack Holley 2300 carbs were sold over the counter under the Direct Connection banner as "Racing" carbs. They were also used on Ford's during the '60's. It takes a bit of searching, but there are still a lot of nice sets out there, especially if you Google Ford set-ups.
Hughes Engines deep ported the intake and stage 2 ported my Indy EZ's. I picked up a very nice heim-joint linkage set-up from Ben at ProMax. I used a wide band to tune them, which makes it relatively easy to get them virtually spot on in no time.
Here's a pic of the linkage, and an old fuel line I had made up. I've since gone to three individual fuel lines. Notice the fuel feed is on the opposite side, as the float bowls are side hung.

Fit under the stock, flat hood of a '67 Dart without a problem.

I agree with this. I would have consider the 6pk setup for my car but if I make any changes since my car is from the Max Wedge era I would go with the crossram. A 6pk on a 63 Max Wedge era car just dont look right to me. Ron
 with both quotes
A 6pk setup on a Max Wedge-era car is kinda functional for the times, but just wouldn't be a Max-Wedge. The two carbs and crossram intake is its' calling card. Both setups make for a excellent street/strip setup other than a well-tuned 4bbl setup. 6bbls work best with medium to heavyweight cars, while the Crossram setup works very well with medium to lightweight cars. As for a2x4 inline setup, they are no less the attention getter than the 6pk and just as powerful, but a bit harder to tune (without the wide band sensor setup). Manifolds too, have to be optimized to the overall combo.

If you can find a set of carbs with the center air idle speed screws instead of on the throttle shaft they are "very" easy to tune.
