The engine was highly modified but intake was un touched stock .
Carbs where new holleys from summit with very little modifications. Car ran like a Swizz watch. Nothing looks better then a Six Pack.
10.71 thru exhaust manifolds and a six inch bias ply Hey, I recognize that car from back when it was in So Cal.

10.71 thru exhaust manifolds and a six inch bias ply I'm not sure if you are just commenting on the car in your post or responding to another post? Regardless, YES! That Roadrunner in your post , dressed as an A12, running that kind of intake manifold and carbs, and exhaust manifolds, and tires, absolutely quite the accomplishment. I would have SO LOVED a car like that, back then, running those 1/4 mile times dressed like that!! It would have been an absolute ATM !!

I don't think there as bad as people think. And yes Troy from SO CA restored the car before I bought it. He did a great job one of my favorites

He just made a slight adjustment to the clutch height to his preference

You would need the Weiand manifold to make more power and a set of mechanical carbs. It doesnt run great on the street unless you do the DC mods.
Tests done for DC and mods

How is it that nobody makes a good single plane 6 pack intake? Try a Weiand S/S intake, tunnel ram-single plane type. End carbs are like the size of a 800 dp and i guess the middle should be close to a 600. So 800 + 300 = 1100 would be more likely, unless those four barrels don't flow what they advertize either. I would say six barrels should flow a lot more than any four barrel except the dominator. Good test for you flow bench guys, just flow half of a four barrel, say an 850 then the six pac two barrel at the same rate to clear the air. , My thoughts too,

I’ll be modding up a two four barrel top for that bottom, two AVS carbs

Based on his testing I'd have to conclude it would be the best multi carb manifold with the added bonus of it will still fit under a factory type hood scoop. Not sure if the OP's idea of 6 pak induction would include an aftermarket intake or not. http://www3.sympatico.ca/big-d/2X4.htmKevin

Here’s a pic of one of the prototype/development intakes for that Weiand. I believe from Keith Black’s dyno. Tom Hoover’s intake concept i believe too. Fabbed in sheet aluminum

HOLY THREAD RESURRECTION BATMAN! Yes, but I'm doing it for an important reason: I have a Bill Mitchell aluminum RB block that I'm having built as a 4.50 x 4.50 572 going in my 70 V-code Roadrunner. I insist on a 6bbl feeding it. I'm also very attached to my N96 Air Grabber hood, so I am going to start out with the Indy ModMan intake CNC'd for Max Wedge ports for the TrickFlow 270 heads. My Holley carbs are modded by Promax. It seems to be the ONLY choice for the combination of low profile to keep the Air Grabber, 6bbl, and nitrous. If I can ever "get over" letting go of the Air Grabber and hood, my next move would be the aftermarket (slightly taller) 69½ A12 scoop. Also I emailed the company that has the 2bbl "Dominator" carbs just to see if they have any info on using 3 in a 6bbl configuration. Do the trickflow 270's have a raised intake port location and what is the height difference between the indy intake and a stock ebrock 6pack? the answers to these 2 questions will tell you if you caan keep the hood , assuming you can get an air cleaner on it assuming this is going to be a street car .
running up my post count some more .

I think there was at least one car back in the late 70’s using the Weiand bass with the 2 x 4 lid on a 343horse 383, I can’t remember who raced it. Back in the 70's Keith Black modified some for dual quad 383 superstockers. Unfortunately I could not find any pics. Years later Dulmage made the lid for his 440 shown in the Simpatico article above. I thought Weiand had a 2 x 4 top for that intake? I know the Edelbrock STR did. Nope. Sixpack and single dominator were the only lids weiand made. If I remember correctly, the dominator lid was created so that Paul Rossi could play in an AHRA single four barrel HotRod class just by swapping the lid and carbs.

In theory, there is no difference between theory and practice. In practice, there is.

The end 2 bbl carbs front bolts allow the 4 bbl carbs to sit in same place so only the inside bolts-holes need to be fabbed up. Wood first then maybe a carbon fiber top. Just thought of sitting my Hemi 2x4 base on it to see if spacing is right. Doing this so I don’t have to break up the stock intake-carbs set I want to use on another engine.
