When I rebuild my 239 I would like to change the stock 2bbl. intake for a 4 bbl. or preferably multi-carb 2bbl. intake. I've seen alot of intakes for sale but have been told in the past that the heads are slightly different on my 239 (intake # EBU....) that on later y-blocks.
Does anyone have a list of the correct intake part for 4bbl. or multi-carb setups that would work on my 239?
Can a later Eddelbrock #553 or 557 or Offy. type be used with some easy modification?
I know the multi-carb set up would have to be de-tuned a bit for the 239 size motor, but they sure look cool!

thanks for any help, Ed

 

You can check out my site at m571.com/yblock, where I've posted some intake manifold pictures, including some combinations that you have mentioned.

Of the three port sizes, the 54 and 55-56 ports are fairly close in size. The 57 and up big ports are quite a bit larger. I did run a 9425B manifold on my 239 for over a year without a problem, but when I tore it down and looked at the contact areas on the gaskets, I was just plain lucky and wouldn't try it again.

Again, as the ports are close in size, you may have pretty good luck using a 55-56 manfold on a 239. If I were doing it, I would want to see the manifold and compare it with a 239 intake gasket before taking a risk, but it may work to use a 239 intake gasket for comparison with 55-56 intakes or heads at the local salvage yard.

 

Hey Ed, you can go to some machine shops, and take the carburetor you want to them, and have an adapter plate made very easily out of Bar Stock. My Nephew that works as a CNC computer Lathe
operater machinist for Hydril here in Houston, ...he was just playing around for fun but it did work...He bought an old rusty 75 chevy pickup with a straight 6 in it, and made an adapter plate out of Bar Stock, and put a V8 Quadrajet 4bbl on it...Hahaha!! It looked very silly, that thing on the side of that six cylinder, but it did work. Janet

 

What year is your 239, please?

 

Hey Loan Ranger....

My 239 is the stock motor from 1954, (intake is "EBU") I think august was the month built.
I just twisted an old brake line when working with the master cyln. so I guess thats a good sign that its time to pull everything apart (down to the frame I hope) and re-do it.

Okay, I have the info written down; I will do some checking through some listings I have and see what I can find for you. I will post it ASAP.

 

I will try to see what, if anything, I can find for you. However, while I am looking this up, I thought the following might be of some helpfulness to you in your search and interchange possibilities:

The Ford Y-block began in 1954 @ 239 c.i.d. and 130 HP. This version was the EBU. It had a 2v carb and single exhaust. The EBV version was used in F100 to F600 trucks.

During 1954, all 239's for cars and some 239's for trucks were built at the Dearborn engine plant. At about the middle of the model year, 239 truck engines were moved to the Cleveland plant. All 55 239's were built at the Cleveland plant.

NOt all parts, however, were interchangeable between the Dearborn engines (both car and truck) and the Cleveland engines. The cylinder blocks, heads, and camshafts on the Dearborn 239's were not interchangeable with the Cleveland 239's.

The EBY version, a 1954 Police Interceptor 239, was actually 256 c.i.d. The EBY was, of course, a 4-v carb; the EBZ truck engine was a 2-v carb.

The Ford stock intake manifold for the U code 239 was B5C-9425-A. The 239 four-barrel intake for the A code engine was B5C-9425-B which was superceded by the B6A-9425-B. The NEW run of these parts--which, according to sources, will NOT interchange with earlier versions--was the ECZ-9425-D which took two original Ford carb numbers EDB-9510-C's. This was begun for the 1956 model year.

The next Ford stock dual carb intake was the B7A-9424-C, used on the 1957 A and S code 312's. The B7A-9424-D was used on the 312's with the supercharger beginning in 1957 as well.

In the 2004 Edelbrock catalog, I find no manifolds listed for any of the Y-blocks at all--although, of course, they still show some parts for the Flatheads. Perhaps you might check with Offenhauser.

I do not have any more specific information than that. I am sorry I could not be of more help than that to you. However, perhaps someone can take the Ford part numbers I have given you in this post and let you know about interchangability either from memory, experience, or from consulting an interchangibility guide they may have.

I do hope it help you out at least to some degree!

 

First of all, you can check the block to get the foundry casting symbol to determine if your engine is a Dearborn or Cleveland casting.

Secondly, I spoke with a couple of friends of mine who have worked on Y-blocks for years and both of them stated emphatically that 1954-1955 manifolds and heads are interchangable--provided, of course, the foundries match.

That should indicate that the B5C-9425-B four-barrel intake should work on your 1954 engine.

I do hope this is of some real help to you!

 

thanks for all the info...I'll keep a lookout for the right intake number now.
