I guess that's what this all comes down to actually. If I can find the carbs for a decent price and get them working correctly I feel like this is within my skillset.
That being said, this truck although not a budget build, is not a WOW (wide open wallet) build either. Right now that's the Jeep. I've got a good running, pretty solid truck that I want to do a mild build on, drop it, clean it up, and drive here and there. I don't need 450 to the wheels, but I can't live with a slug either.
I really do appreciate all of the input from all of you, I know I am a neebie, but I've been a car guy my whole life and a Ford guy since jump (my first ride was a '75 F100 XLT Ranger 390, miss that truck).
We'll see if I can find the carbs, if no, then maybe I save this part for a future build, gods knows there will be one (speaking of, anyone know of a good solid '64 Galaxie?)

Thanks

 

FWIW, the teapot or whatever you want to call them Holley 4000s for the E code 312 had special primary boosters to reduce the air flow and increase venturii vacuum. They had a "skirt" like the 735cfm 428CJ carbs in 69-70. With those and a pair of teapots you can make the special carbs. I don't know of any other carb can be made to fit due to the very close spacing of the flanges.

 

Re the spacing, there are solutions. A pair of 390s in a stationwagon that performs very well:

 

That's what I'm talking about!!!

 

Guys,

A friend of mine in Norther WI is a big E-code enthusiast. He's got a bunch of them and can help you out with picking out a good combination to make it run. He's also got a real good source for rebuilding the t-pots as well.
Let me know if you want to talk to him and I'll get you his contact info.

Nick

 

Definitely.

 

I think this is a case of overcarbing. You can do what you want. I wish you the best but I hope you realise this is a money pit for anyone not intrested in draging.
There is no reason to run this manifold on a street vehicle unless one needs that much of an ego boost.
Good luck, I am off of this.

 

I just want to say thank you for your input and opinion. Even though I am (may) still try to make this work, I really appreciate that you took the time to respond and give me so much info. Honestly you have done a lot to change my opinion about whether or not to use this piece on this project. I still WANT to, but it just may not work out without my extending my budget significantly which I can't do right now.

So thanks, and please post again if you see one of my threads. I value your opinion (and all opinions honestly).

 

Yes me also. PM me the Tea-Pot guys info please.

 

See if you can find some Carter WCFB's . I ran them instead of the Flaming Towers of Death { teapot holley }. Some of the Mercs of the day had them installed. Mine ran very well with great street manners and exceptioal performance from a 292 bored 0.040 over General Kinetics cam , big valve heads, hi ratio rockers, in a 55 Ford 2dr sedan with a 4spd top loader and 3:89 gears. I wish I had that car back!

Have A Great Day ------ Hotwrench

 

I installed a '54 Mercury carb and manifold on my '54 Customline with the 239 engine and it ran great. You could feel the secondaries tip in and that little motor would really go. It was pretty guick and then the 265cid Power Pack Chevvies started to dominate the street scene.

 

B7A9424C .. Dual Quad Manifold / VIN engine code E.

Original applications: 1957 Ford/Thunderbird/Mercury 312.

This manifold is very desirable, especially to the T-Bird crowd, is very hard to find and worth mega bucks.

These came factory installed, or were available at the parts counter.
------------------------------------------------------------------
There were three different 'valley pans' (Push Rod Covers).

B6A6519A .. Push Rod Cover / 7.32" wide / 9.06" filler tube length / Not used with Dual Quad Manifold or with Supercharger.

Fits: 1954/57 Passenger Car 239/256/272/292/312 / 1954/57 Truck 239/256/272/292.
-----------------------------------------------------------------------------------
B7S6519A .. Push Rod Cover / 7.32" wide / 7.56" filler tube length / Has opening at rear.

Fits: 1957 Ford/T-Bird/Mercury 312-Use with Supercharger only.

Fits: 1958/59 Ford Passenger Cars & Trucks 292.
------------------------------------------------
B7A6519B .. Push Rod Cover / 7.32" wide / 6.48" filler tube length / Has opening at rear.

Fits: 1957 Ford/T-Bird/Mercury 312 / Use with Dual Quad Manifold only.

 

Now I need to find a pan... :-/

 

As several have pointed out the old teapot Holleys can and will catch fire, but only if they are leaking fuel and the engine backfires. Lots of off-road guys used to like them on Jeeps as they will run well almost on their sides. WCFB Carter carbs, they are mechanical secondaries rather than vacuum. As a result it is possible to open all 8 barrels by standing on it. They will also backfire, but since the float bowls are concentric around the venturiis, it usually isn't as spectacular. They are also easier to find air cleaners for.

Rocker arms, if you can find a set of 1957 rocker arms, they are the highest ratio of all the Y-blocks.

As for over carbureting, yes, it is easy to do, the problem with multiple carburetor setups is most people don't realise that many of the factory dual quad or three dueces used rather small carburators. I succesfully ran dual quads on a 289, but they were on 465cfm each. Properly setup and with a good flowing exhaust system, it can be a fun system. BTW, 289 with 3:89 gear in a 66 GT350, got 22mpg at 70mph and flew.

 

But if I'm not mistaken, they have a vacuum operated air valve above the throttle butterflies, like the Edelbrocks, (or Rather the Edelbrock is like the WCFB) so that the secondary airflow is still operated based on vacuum. So they're not quite mechanical like a Holley double pumper.
Is that right?
