Hi Guys, First I'd like to say , for my first experience with a y-block, you folks rock, I have benefitted from all your years of experience, and I thank you all ! I purchased a manifold from ebay, stock, cast iron, ECZ9425A, got a great deal i think, $65.00 including shipping.  Can You recommend a good carb? This year the engine will be more or less stock, except for Headers.
Thanks yet again, Mike

Just to point out that if you want to use the newer carbs with the square pattern you will need an adapter.That manifold only takes the teaot carb used in 55-56.

will it still be efficient with an adaptor?

A Carter WCFB will also bolt onto this manifold without an adaptor.
What size Y-Block do you have? This manifold should work OK with a small Holley with the adaptor. They were used in '55 and '56.
May I suggest since you are new to Y-Blocks, ask before you buy. The 'B' manifold is much better.

If you get an adapter for a later model carb, you will need the later model distributor also. The teapot Holly was designed for a vacuum advance only distributor. A later model carb will be designed for the later model centrifugal and vacuum advance distributor.

Look for a Ford/Mercury/Lincoln specific WCFB. It will have Ford linkage and a secondary vacuum diaphragm.

If you use the WCFB you will have to find the correct air cleaner to fit the WCFB as the base opening is smaller than a Holley teapot. You will also need the distributor vacuum line as the WCFB used a long brass nut at the carburetor end. The regular type brass that is used on the teapots is to close to the WCFB carburetor to use your fingers or wrench to tighten.
WCFB is good carb just many pieces and secondary diaphragms very hard to find.

Rochester carbs from mid '50s gm cars will also fit that manifold, but availability and parts are probably an issue.

ok ok, i get it (waves the white flag) I will run the 2bbl till i find a better manifold. Does edelbrock make one for a 272 yblock that is still available, and that takes a newer carb?

Mike,I don't know if you are after performance or just a good running 4bbl stock motor.If you just need a good 4bbl manifold that accepts all the newer carbs you can use ECZ-9424-B(not A),I am sure someone on here can sell you one if you put a "wanted" in the classifieds.Don't feel bad about the one you bought.Someone who wants the correct manifold for 55-56 I am sure would buy it.Put it back on Ebay and see what happens.I took that one off mine after spending $400.00 to have the original carb rebuilt and being unhappy with the results.I put the later "B" manifold on and a 390 cfm Holley along with the later dist which must be changed when you swap manifolds.The "B" manifold was available on the 57-up Y-block along with the original Holley 4150 carb that is still around today although improved as the years went on.if you want any info or suggestions post a question on here.You will get all kinds of help.

Long Island Mike - Instead of getting hung-up on getting just the "right" manifold - why not use the nice "9425-A" model you've got, and put on an adapter to fit the later style of carbs? The Y-block manifods aren't so hard to change out - and so long as you use the throttle mounting bracket holes on the "A", the later type "9425-B" won't be any trouble to fit on there later. Mounting holes are a match and so on. Speedway Motors (and others) sell the adapters - the Speedway part number is 135-1935 - they were $14.98 the last time I gathered up a catalog. If you find a 9425-B later on and still want to make the change - go for it -your carb and throttle linkage will swap right over.

Adding to what Steve suggests - you will probably need a spacer with either manifold. The adapter kills two birds with one solution; it allows you to use the intake you have and it performs the spacer function, too.
I hear good things about the Edelbrock/Carter AFB 1403. As has been mentioned, you can get a rejet kit and tune it to your engine.

And the holes will probably be better with the adapter. I have a B manifold and a Holley 390 and the manifold holes are a lot bigger than the carb holes. I put a piece of pipe inside mine to make them a little smaller. As said about the distributor, well, it will just work a lot better with a late model distributor and they are thick as fleas on ebay (except when you need one). Mine's a 272 and has, as I said, the 390 and a '59 distributor with a Mallory electronic unit and MSD 8mm wires and it is sweet!

The dist are available from Autozone for one example.Ask for a dist from 64 F100 pickup with 292.Last year used.You MUST change distributor if you go to a later carb.The original will only work with 55-56 carb.(Loadomatic).I did mine and used an accel electronic kit.I am also using the Holley 390 but with a phenolic spacer and "B" manifold.Works MUCH better than the oriinal setup.
