Technical Winters Small Block 1966 Intake Manifold.

Perpendicular thinking… do any of you remember in the 80s I think, there was a 2-2barrel setup being marketed that used 2 Weber downdraft carburetors? I thought those looked pretty cool! And Webers are extremely adjustable, which might be good or bad depending on how much you mess with them.

 

Webers are mainly designed for Individual Runner (IR) applications.
I guess they could work, but the Inglese setup is probably superior.

I prefer the vertical ones to the sidedraft sideways style.

I didn't find any dual 2bbl intakes. I looked around and found a triple Weber intake for you!

Was that 2 Weber setup for Small Block Chevy's? I don't believe I seen anything like a 2×2 Weber before, any pictures.

I don’t remember a two, two barrel Weber manifold but Jim Inglese offered this inline setup for the SBC-


Here’s photos of the Inglese angle drive for the distributor, I posted these a couple years ago, disregard the arrows.

 

Isn't that something, I wonder if anyone ever ran one of those on the street, a buddy of mine was a Weber Freak he always said they were the best carburetor made. I don't know about that though?
Good to see you again Fordors.

Got curious cause I was certain that I had seen something using dual down draft Webers. Sorry I’m such a computer illiterate person and can’t figure out yet how to get links in a post. Anyway, I found this right here on the hamb:

This was in the for sale section about 10 years ago. It was made by Claude’s Buggies. Something tells me that it was not a popular item…

Those carburetors were Weber 48 IDAs. The add mentioned that the intake an open plenum, probably not the best design for a street driven car.

It does look interesting though…

 

Definitely different, I'm GM old school so Winter's, Edelbrock, Offy, SAY WHY-AND, Rochesters, Carters, Holley & a few other's are my drug of choice, still like the other Two of the Big Three High Performance ALL American Made Power Machines.
Just can't beat AMERICAN MADE MUSCLE.

This thread has wandered, as threads of this type often do. I would like to go back to the original manifold and acquire more information.

I think the information exists ! I just don't have the sources anymore to check.

Will do some speculation here, and perhaps someone with current sources might take an interest.

The intake manifold carries a part (or casting) number. GM rarely, if ever, built even test pieces that did not have a GM number. So GUESSING there were GM, in this case Chevrolet, part numbers assigned to the Holley carburetors that were used. Since the item did not go into production, the numbers did not make the parts books, or some of you sharp-eyed Chevy folks would know them. But does anyone have any of the Chevrolet cancelled part number files?

Similarly, GUESSING that Holley would have issued list numbers for the carburetors, and drawings and bills-of-material would be issued for IN-HOUSE use. Since the carbs did not make production, the list numbers would not have been included in the Holley "Carburetor Number Listing". Have you ever looked at how many list numbers are skipped in that listing??? I have quite a few in my database that are not in the listing.

But I no longer know anyone in the Holley organization that could be helpful; the folks I knew left the company decades ago.

I don't know nearly as much about Holley as I do Carter, but will give a Carter example. Fairly common knowledge that Pontiac used a pair of Rochester 4-GC carbs as a dual quad in 1956. Less common knowledge is they were cancelled not because of performance, but because of service issues. And much less common knowledge is that Pontiac tested 2 different sets (one for S/T, one for A/T) of WCFB carbs for 1957 (Pontiac service personel were much more familiar with Carter than Rochester at this time). Unfortunately, these did not go into production; again, not because of performance, but because Pontiac management instead opted to take a page from the California hot-rodders and go with tri-power. OK, enough with the history; why is this useful to this thread?

Because, even though Carter produced ONLY 6 sets of each S/T and A/T pairs, both Carter and Pontiac issued part numbers for these carburetors. And if you look in any released to the public Carter or Pontiac publications you will not find these. Fortunately, I was able to acquire a LOT of in-house Carter information. My Carter carburetor list has practically zero number skips from number 1 to the end of Carter carburetor production other than designed blocks of numbers that were reserved for other than carburetors. I have a copy of one of the original Carter drawings for one of these carburetors. And of course it is stamped CANCELLED. And the individual part numbers made the in-house occasionally published "parts interchange list" so it was possible to construct a bill-of-material for the other three.

I fully intended to build a set of the 1957 Pontiac dual quads (I saw one original set maybe 50 years ago), but just did not have the time.

As my sources at Holley decades ago were able to find information on another project (I cannot comment further on this one, other than it was not Chevrolet); I simply cannot believe Holley number assignment was that different from Carter.

Perhaps someone has the connections to acquire this information.

Since Holley has been sold over & over they do not have much information available, ever time I've tried to get information on many of the late 1950's & the 1960's High Performance Holley Carbs or just a Regular Holley Carb the folk's at Holley can't find the LIST Number's, in fact YOU have helped me so much more than Holley has in the past with several of my Holley Carbs.
Two of my Holley Carbs YOU helped me with when no one else could, my early Ford Holley 450 cfm & my Chevelle 1966 over the counter replacement Holley 780 cfm & YOUR the only person to have the correct Holley Carb kits to rebuild both my Holley Carbs (THANK YOU).
The sad truth is Holley isn't the same anymore with different Holding Companies & so on acquiring Holley over the past 30 years or so & other 1960's Speed Part Companies going over seas to make cheaper part's.
Many of the original American Speed Part Companies started in basements & garages by the Old Time Racers & their families have sold out & all there paper work is destroyed or who knows?
You and other folks that lived & was a part of the 1950-60-70's Hot Rod Scene here on the HAMB have been helping me for year's with tidbits of Vintage Factory Speed Part Identification more then anybody.
A Big Thank You to Y'all that have saved all kinds of Hot Rod History.

Dustin - I am happy that I was able to help you in the past; these forums are good for that purpose. And there is some truth in your post above but not all is lost (yet).

TONS of information on the Moms and Pops you mention, as well as the major players has been posted on these forums. But the problem for future generations, even for us today, is that this data is organized by threads as it was posted, not in a totally indexed environment.

When I started searching for carburetor information for my business in the 1970's, Harrah's library, and the Detroit library were known to specialize in automobile information. After contacting each, I was dismayed to find I had more carburetor information than both combined. When computer scanners became affordable, I began scanning carburetor data in my possession. Twice I have sent thumb drives of digital carburetor data to the AACA library; the most recent submission, which will be my last, was 110 GB of data. While pretty well organized, I have no doubt the professional librarians can do it better, and this data will be available once I am gone.

I would highly urge anyone with any of the unusual data, to submit it to the AACA library.

One of my all-time favorite quotes is attributed to Amadou Hampâté Bâ and paraphrased: "when an old man dies, a library burns to the ground".

Well, my library is NOT going to burn. I hope others will do the same.

Jon, I am sorry if I was part of the wander, just trying to share.
I did not have any useful info for you and therefore went off the path.
I am glad to hear that you have collected AND shared the info you have.
While there is a vast amount of info buried in threads here, it beats other social mediums for at least tracking it down.

Dave, you found it! That one is wild. 48s are still available. I remember seeing a brace of 4 on an intake for a Ford Mk.IV that were described as unobtainium. 52s, maybe? This was in the 80s at the Early Ford Store in LA.
