I'm seeing so much info on the web about intakes that "will work". Is there a solid part/casting number out there that I can trust? I know Mummert and blue Thunder make one specifically, but maaaaybe I can find one online that i can clean up and paint myself and save a little dough if I have the right numbers? Anyone one here have one that they're willing to part with? Currently running with a 2 barrel carb/intake and it's just not what I'm looking for.

Tealy, search "Ford Y block Intake Manifold on ebay. You will find photos of the 1954-56 "A Series" and 1957 "B Series." The smaller square flange 54-56 manifolds accommodated the Holley 4000 "Teapot" carburetor. The 57 "B Series" has a wide flange that will accommodate 57-up carburetors. You want the B. If you go with a 57-up carburetor, you will need a 57-up distributor that has both vacuum and mechanical advance. The pre-57 "loadomatic" distributor is vacuum-advance only. Ted Eaton (eatonbalancing.com) has an article on modifying the Teapot carb to work with 57-up distributors, but the 57-up carbs won't perform well with the Loadomatic distributor.
Keep in mind that the Ford cast iron manifolds are heavy; shipping will be expensive. Mummert's aluminum manifold (ford-y-block.com) is cheaper than the Blue Thunder, but it does not have the heat crossover for the choke. If running an electric choke, there's no need for the crossover. I have a B intake, 4150 carb, and 57 distributor. I intend to block off the crossover to prevent the exhaust heat from burning off the paint, which is common. There are aftermarket intake gaskets/w smaller crossover hole, the purpose of which is to reduce/eliminate burning off the manifold paint, but I will block off the crossover, which can be done at the heads or on the intake.

It would be helpful to know your location. Adding your location in the signature section in your profile would solve that. As previously mentioned, shipping costs can make what looks like a good buy suddenly not so good.
Be careful looking for just the ‘B’ intake as the 1955 4V intake manifolds also have a ‘B’ on the casting number suffix. The desired cast iron 4V intake manifold would be the 1957 & up ECZ-B casting.

While looking for the intake manifold casting numbers, I did come across this older thread showing the horsepower differences between some of the various 4V intake manifolds. Here’s the link to that thread for those who are interested.

You don't state your location but that can be a determining factor for blocking off the exhaust passage or not. Just something to consider: This morning it's 44* in Michigan and I may take my 64 truck for a ride. Having the exhaust passage wide open helps greatly in warming up all that iron more quickly. Others have helped their vapor problems in warmer climates by blocking the exhaust passage off. Also, I see you have a 64 F100 so you have, sor should have the latest Y-block distributor already. Good luck with your truck................

I have a modified 57 B manifold for sale in the classified section. Elongated two intake carburetor ports, opened up/port matched the runners. It ran really well on the 312 I have.  I bought a BT intake reason for selling

yeah, I'm in central Florida so cold isn't really an issue that I have to worry about too often. 
Thanks everyone for your input. I'll do another search looking for that "b" mani and see where I wind up. I appreciate all your help!

Look on ebay for the 57 and later manifold. I see them there often.

I recently checked the shipping estimate on a manifold from Indiana to Minnesota, it was $42. From Here to Florida would probably be in that area. I do have ECZ-B manifolds to sell if you are interested.

Hey Hoosier, I'm interested in an ECZ-B manifold if you've got a nice one that'll fit up nice on my truck engine. Can you DM me some pics and a price? $40-$50 shipping is a reasonable for sure.
Thanks!
ps. what part of Indiana are you in? I grew up in the Southern part, down by Bloomington. All of my family is still there...freezing. LoL

I think the actual part number is 9425-B, might make searching easier.

The part number is ECZ-9425-B for the '57 cast iron 4V intake manifold. This is the best of the cast iron intakes for the Ford Y. The 9425-B number is used in many of Ford's other engine families for their intake manifolds. Joe-JDC

Sounds like something Ford would do!

Joe is correct regarding 9425 being used by Ford to identify part as an intake manifold, but not necessarily a Y-block manifold.
Joe, in your 2nd photo of the bare manifold, there is an indentation/recess in the lower-right corner of the photo. Although I've seen a number of photos of intakes/w plenum opened up to two ovals (Ted said he routinely does it), this is the first one I've seen with that indentation/recess. What is its purpose?
Thanks

If I understand your question; by the look of it, the lower passage front pair is fed from the top opening in the manifold and it saves cast iron. It’s the reverse on the rear of the manifold which I think you are inquiring.

I'm referring to the notch/recess/indentation at the lower-rear edge of the carburetor mounting surface. Maybe there was a clearance issue with the distributor.
I got it. The recess is an integral part of the intake manifold casting. Maybe it's the light/angle, but it looks different in JDC's photo. I went back and looked at Richard's photo of his modified 57 intake for comparison purposes. The paint helps to distinguish the plenum's carburetor mounting surface from the runners. You'll have to back a few months in Classifieds to find Richard's intake.

Wanna trade? Just kidding, but I do intend to have mine done. Years ago, my machinist friend opened up the plenum of my 289 manifold, and I gasket-matched the runners. Hopefully, paying to have my Y intake done will be cheaper than Mummert's aluminum intake; otherwise, I'll sell mine and buy Mummert's. My only concern is limited hood clearance on my 55 Tbird. According to John's description, his Tbird intake is still a bit taller than my 57 intake. A dropped air cleaner is necessary when using a carb spacer.

The "B" manifold fits fine in my 1955 TBird. I also have a 1/2" PCV spacer under my Holley carb. The stock TBird air cleaner will work also. I use a custom air cleaner. According to the Mummert website, he sells an shorter aluminum intake for TBirds.

By milling the carb pad down like the picture above, it allows you to use a phenolic spacer to keep the carb cooler and run a PCV if you so desire. The 1" spacer with the PCV fitting is available from CASCO or Larry's Thunderbird. If you are willing to use a different air cleaner on the Thunderbird, you can install a 1" spacer without hitting the hood. Joe-JDC

On the 2019 EMC 303 Y, with iron heads that flowed ~245 cfm, we made 437 hp with the ported ECZ-9425-B iron intake shown in the picture. Not bad for a little Y. The fully ported Mummert made 454 hp, and with the new SP the same engine made 463 hp. All that with 10.4 compression ratio. Joe-JDC

In Joe's and Phil's photos, the air cleaners are smaller in diameter than an OEM Tbird/Ford air cleaner and considerably smaller than a 14" round/oval air cleaner. As far as hood clearance on 55-57 Tbirds is concerned, that needs to be taken into consideration. A Summit 14-inch round air cleaner/w drop base and 3" element will allow enough hood clearance for a 1/2-inch carb spacer. On the other hand, my Billet Specialties 15 x 8 1/2 x 3 oval air cleaner, which does not have a drop base, will barely allow the hood to close/w no carb spacer.
According to ford-y-block.com, the Mummert Tbird intake manifold is 0.180-inch taller than stock.
If you have a modern Holley carburetor, the PCV hose can be attached to the carburetor, no need for the Casco spacer.

The 14" drop base air cleaner will only work with Holley style carbs. It doesn't work with the Summit or Edelbrock carbs where the fuel line is off the top side of the carb. Joe-JDC

By 55blacktie - 2 Years Ago

I can see where using a drop-base air cleaner could have a clearance issue with the Edelbrock carburetor fuel inlet, but I don't see a difference between the dual-feed inlets of my Holley 4150 Street Avenger carburetor and the dual-feed Summit carbs. When I test-fit the Summit air cleaner on my Holley carb, I did not observe any clearance issues. I have yet to install the carb and air cleaner on my car, so I will check for clearance issues again.
Installed Holley dual-feed hard lines on the Street Avenger carburetor and installed the base of Summit G3000 air cleaner. No clearance issues.
If you look up SUM-G3000 on Summit's website, you'll find that it is stated in the description that Edelbrock and Carter-style carburetors require a spacer. There's no mention of the Summit carburetors requiring same.

I’m curious: Joe has retained the ‘55-style two part OD shock absorber throttle rod assembly, but Phil has the ‘57-style single rod. I’m wondering why they changed the design when they went to the larger Holley carb in ‘57 (?). If both designs work equally well with the later carb, it must have been a cost saving issue, unless Joe’s carb is somehow better suited to the earlier linkage (?).

Oops. My error. Photo shadows & perspective distortion rather deceptive. Closer inspection demonstrates Phil still has (essentially) the orig. ‘55 linkage. Parts on both setups seem juggled a bit from stock though.
Studying the ‘55/‘56 throttle assemblies DOES make me curious about one thing: The bellcrank/linkage-articulating part (7A185) that bolts to the intake manifold has two ears (with bolt holes) that stick up. Yet, I can’t find any indication there was ever anything to be attached there (?). Puzzling.

I had to install three washers under each bolt that holds the stand on the intake manifold to raise it enough to make the stock linkage work. I also had to extend the turnbuckles almost their entire length. The accelerator pedal arm had to be tweaked a bit, but it all came together and works decently. My accelerator pedal rod has been welded at least three times in the past, so it may be part of the problem getting everything to fit together well. A 3"x14" K & N filter assembly with the drop down base will work with a 4150 style Holley carb where the fuel lines drop down and not to the top side of the bowl. I installed one of my 735 CJ carbs on the engine just to see if it would work.   Joe-JDC
