But 2 4s? "The 302ci V8 was factory equipped with dual four-barrel Holley carburetors"

It's for sale for $200,000
Nope no 2x4 from factory
Pictures show one carburetor
Interesting the owner didn't know what was under the big air cleaner......
I'd say it was more than likely just a brain Fart. I have 2x4's dancing in my brain All the time, as I really love them as can be seen in these pictures.

I too am a believer in 2x4's in a '68 GT350. I have been for some time. Mine is a C60A-A, aka, the T/A intake for the Windsor heads.
You've seen mine before but I don't mind showing them off again.

Just Curious, will the 197 GT 500 Air Cleaner fit your Small Block 2x4 Intake set up?
Technically no as built. The top and filter do but because the intake relocates the carbs, it requires a custom base plate.
Here is what I did with that, but I combined it with the KR "ram air ducting" on the hood.
I love 2X4s, but my favorite is my '60 Chrysler 300F.....

Kool but I could have fit eight more carburetors on that engine.

Yes, lots of room on that 413, but man, it gets 10 MPG now, I would hate to think what more carbs would do to that......

Well speaking from my own experience with running a set of Weber 48 ida's, a 750cfm Holley on a 351C was getting about 12mpg no matter what I did.
The Webers on the other hand, were capable of about 22mpg.
So my thought is it depends on how well the engineering is which is another way of stating how "efficient" the design is.
Chrysler was thinking "outside the box" on that cross ram design and had the guts to show it to us all so kudos to them for that.
As far as the 2x4 Holley set up, consider that in my case I am running 2 1850, 600 cfm vacuum secondary carbs. Basically stock.
That particular intake manifold is somewhat of a hybrid in the sense that at WOT, the runners are all equal length with what even now is thought to be optimum distance from throttle to valve.
At idle, it runs on ONE 1850 "stock" Holley. So it is quite capable of delivering upper teens mpg wise but also capable of "Bonzi-death wish" Trans-Am "I am trying to kill myself" flat out running.
That IS what the thing is engineered for and is quite efficient at delivering.
You have to have actually witnessed in person the nature of that type of racing to understand completely my comment.
Thanks and I will take your word and much more experience about "that kind of racing". My only racing experience was old school drag racing, pedal to the floor stuff. And more new style Texas Mile type, WOT, pedal to the floor to join the 200 MPH Club. I don't like curves, braking, and having to slow down...... ;)

Nice pictures of my favorite subjects Roy, but I have a strong feeling that last picture is an old picture. Just call it intuition.
:)
Hey John, just a picture for reference for those that don't know. I thined that heard by 3 but still have more. Did you get the tags yet?

Not yet, YES! AND I WAS excited to get them however. I've been "thinning" the herd as well recently. The Mini-Plenum moved on to a friend of mine that is going to use it. The Dual Dominator intake and associated carburetors are heading to a race track in the future. I just had to find another offset distributor to make that deal occur. But yay! I knew where to go for that. Temporarily ill have three offsets unless the third one arrives after your old unit leaves. With the help of the group that purchased the parts from you I was able to get six T/A distributor bushings made.
No the intake that was 4th from the left side in your picture is not going anywhere, it is going to be on the 1969 1/2 BOSS 302.
