Wouldn't be hard to make a Weber intake from steel tubing and flanges. Use a fiber insulator/spacer between carb and base to prevent too much heat transferring to carb. If I were going multi carb that's what I'd do -- one barrel per carb has wicked throttle response as long as the carbs aren't too big. Three sizes of IDF (newer IDA replacement) are available, and there is the DCNF also. I don't know enough about Webers to say a whole lot, but the venturis are replaceable at least on the DCNF, making them size adaptable to almost anything.

I you want to make as nice looking 3 x 2 intake start with an Edelbrock 3 x 2 intake for a 383 Mopar and graft it into a AMC Performer air gap base like other have talked doing with 383 Tunnel Ram intakes. If spent some time and effort you could build something that looks very original. The average person would never know it wasn't a factory built aftermarket 401 3 x 2 intake.

Wanting a 3 X 2 manifold is obviously for the cool factor. A single 4bbl or a dual should make more power. A mod man with a 3 X 2 top is the best and easiest way. But if you want to go through the hassle of grafting a MOPAR tri power on a air gam base then go for it. If it don't leak it will obviously work just fine. |

If, big IF, you had blower intake laying around - you could mill the top support off and just use a flat plate to fab for the 6 pack.
Not much machining or time. Not going to be flow generous, but easy and cool! A six pack set up with mechanical linkage to open the outboard barrels works well. Converted GM and Chrysler away from factory vacuum systems this way and you get much more reliable/efficient performance. Better then a straight up 4 barrel if set up right in most cases. If I had the intake I'd do this myself. But a new blower intake is over $1000 - not me! Ron, some have the time but don't have the resources, but some have both. Just thinking out loud again.

The regular Offy single plane 4v has a big flat section in the middle, much like the Offy 2x4, plenty of room to open up the cavity, add a plate and have 3x2 for a little more effort but a lot less $$. Someone turned an Offy 4v intake into a blower intake at some point in the same way, too bad the Offy 4v's aren't more common around here or it would be a fun little side project.

Not plenty of room if it is 3 Holleys, but it can be done. Two Carter AFBs fit better. But 3 holleys can be done if you carefully mill the top off, slot it properly and make a top. Second to the Mod Man the Offy holds the best opportunity for a 6 pack and is a proven design. |

You know what, If I could get a minimum of 5 orders I might think of making 3 Holley tops for the Offy. All CNC machined. Your manifold and I mod it. No welding involved. You get it back leak free with bases for 3 Holleys. Making it fit and work would be your problem of course. I think it would about double the cost of buying a new Offy. I am NOT advertising, but seeing the response to this thread I am thinking I can help. |

Seems like a fair offer BB Can you still get the Offy's new? Summit lists the 2x4 and the spreadbore, the spread bore comes up as $314 for me, but not available until next year: I'd assume the spread and square flange intakes start out as the same casting, but I really don't know that for sure.
