Opinions... 2 4's or 6 pack?

I only ever worked on one dual-4, and it was in a Bucket-Tee with a 350Chebby and an automatic.So,I'm gonna be arm-chairing here.
And what I am gonna say, applies to a streeter only.And my experience is mostly with stick-cars. If you are gonna install an auto and keep it an auto, then almost anything will work, with a well-matched TC.

I have to agree with Rocco, and here is why.
Lets look at the 2x4;with 3.55s.....And probably 28s or better out back?
If you go with a stick, you will want a progressive linkage on multiple carbs, or it will be hard to drive away smoothly. And with manifolds,quiet mufflers,and probably a little rumpidy cam; the engine may be a bit sluggish through the midrange.
So now,the 3.55s/28s/ and sluggish midrange, but tricky to drive multi-throats, may conspire to make operation below 30mph less than comfortable in any gear except first gear; which will be 3100rpm.If you can get the progressive linkage working just right, this may not be a as big a deal as I am thinking, But with my limited experience, I would suggest sticking to an automatic and let the TC absorb the grief.
With the 6bbl,we have a different problem in a stick car. If your rear tires hook; the secondaries will probably not open until about 25 mph and of course 65mph is coming up in about 3 to 4 seconds. So if you are after the looks;great but you may be disappointed in the zero to 25mph with a stick car.
Now if your tires go up in smoke, none of this applies and if that is what you are after,either induction will be very nice, but I would favor the 4s.
So now let's talk about Rocco's hard-to-beat single 4.
This is a great idea! Especially with a spread-bore. The smaller primaries with a stick and 3.55s is a game-on combo. Excellent drive away, not so much torque that every time you step on it a lil too hard,your neck hurts,and if you pedal it a bit those big sewer dumps out back will power you up to the speed-limit in about 4 or 5 heartbeats. If it spins, all bets are off.
Now if you are after the excitement of howling tires and smoke, then a single-4DP carb is your answer. With this guy, it easy to control the torque delivery, and so maintain the excitement as the tires heat up and start to wanna hook; just roll in a bit more throttle as that happens. The bigger primaries are welcome on a small-block, but on as big an engine as you are building, Ima thinking any size will do.Again recall that I am talking about a street stick car.
As an aside, I'll never go back to an automatic. There are just too many fun-times to be had with a stick. If I was a laid-back,arm-out-the-window, kindof guy;ok then an automatic might be on the table.Or maybe if my engine had a preponderance of torque;maybe. But I just have a lil 367, and it wants to be on the torque curve all the time to be ready for anything. This requires tight tranny ratios and plenty of rear gear.oh an an adjustable "stall" in case I start at a lil too low an rpm. Just a lil pedal and it is blast-off time.
You on the other hand,WILL have, a preponderance of torque, which will cover a multitude of issues we SBMers have to deal with.Basically you only issue will be to not release too much torque and thus over-power the chassis.
So that brings me to the parting shot;All three of these inductions can be made to work.Two have KILLER looks.One may be a lil disappointing.One may be a bit troublesome to drive. And one comes in a plane wrapper but has killer performance in a streeter. I know which one I'd choose,
And we haven't even talked about justifying the cost of that 6bbl
