There is not an adapter. But it looks like you can achieve your goal with two,

The new carb will not provide the correct signal to the distributor so you will also need to swap to a '57 and up distributor.

Yes you will have a problem with the distributor. The carb and distributor work together for advance. If you check there is probably a vacuum line running from the back of the carb to the distributor. The setup is called a Ford Lodomatic.This problem can be solved by going to a later model distributor and installing a oil pump from a 272. You'll have to change the drive gear from the 239 distributor to the new distributor also. I think all of this has been covered on this forum, so do a search on that. Your best bet would be to rebuild the 239 carb. It looks like it is a Holley 94. It's a simple carb, easy to rebuild by yourself. Speedway Motors sells a kit for it. They also sell air cleaners that you can modify to use your chome cleaner. Another place to check for 94 carb parts would be Charlie Price Vintage Speed. I hope this helps.

  Good luck!

If you are going to use the 2300 carb, you will have to change the distributor. The original carb worked pretty good with the original carb but the 239 distributor will not work well with the 2300 because of the difference in the vacuum operation.



The early 239's had different number of teeth on the drive end than the 272 and later distributors. They also had a different oil pump drive. If you use a later distributor, you will have to change the gear to the 239 one and the oil pump to a 55 or later pump.



I don't know if the 55 239's had the 54 style pump drive and the different drive gear.



The issue with the later carb is the distributor as mentioned above.

OK thanks you guys.  I after I read that I was wondering if there was supposed to be a vacuum line tying the two together.  I wasn't sure though, I don't think I have any original pictures of the motor before I tore it apart but I do remember that there is infact a vacuum line still on the distributor.  I think at one point I did look at changing out the drive gear on the end of the distributor, but I think it was more so I could reuse the one from my 272.  Because that one has all new points, rotor, cap, wires, ect.  Well if there is that big of a run around all to get the Holley on it I might as well go to the original.  That way all I have to do now is link up the throttle instead of redoing everything.

I was also thinking about the distributor gear and the oil pump changes and thought wouldn't that also mean that the cam will also have to be replaced?  Which just makes the carburetor change all the more impractical for me.

While we are on the subject of fuel delivery.  Does anyone know if there is typically a problem with the switching of the timing chain covers?

Because I have the cover to my old 272 (the one for the trucks) on this 239.  Everything bolted up just fine but I thought at one point a while back I heard about there being a problem with the fuel pump?  My new pump went in just fine but I think I heard someone say that the pump gets worn out prematurely because of the arm being overextended?  Does anyone know for sure.

Thanks,

I don't know why you would have to change the cam unless for better performance with a bigger 4 bl carb? 

I've never had that problem with a fuel pump. Installing one can be hard if you don't get the arm engaged with the eccentric just right.

As far as the timing cover goes, a lot of the y block parts are interchangable. It sounds like that is one.

The way I think of it is if you were to change the gear on the end of the distributor from 13 (239) teeth to 14 (272) teeth, that would also change the gear ratio on the end of the cam?

I was thinking on the fuel pump more and was thinking that the only thing that I could think of as being the problem is the cap that bolts to the end of the cam (the cap that pumps the arm of the fuel pump).  I was thinking that if there is indeed a problem with the fuel pump that maybe those caps are different diameters from the 239 fuel pump to the 272 fuel pump (239 fuel pump the glass bowl is on top with the sraight arm going upwards, and the 272's glass bowl is on the bottom and the arm goes upwards but has a slight bend in it).  I was thinking maybe those cap are different diameters, 239's is probably bigger?

Does anyone have any idea?  Thanks

All the fuel pump eccentrics for Y blocks are the same.  The distributor gear needs to be the original to the engine to match the gear on the cam.  If you are taking out a 13 tooth distributor, the 13 tooth gear needs to go on the distributor you are going to use.  The ratio between the cam and distributor gear is 1:1.

Ok they helps and makes more sense.  I guess I will assume that the fuel pump will be fine.  When I get to trying to start it for the first time I guess we will find out right.  I might even check it out before my truck is painted and put together to make sure.

Ok so this last weekend I was sorting through and organizing my parts.  I got to looking at the carburetor and air cleaner and well I currently don't have an air cleaner that will fit the 2bbl bottle neck carb that originally goes with the 239.  Now my dad did point me to one of his old carburetors and air cleaners that he had for his '55 or '56.  The carb. looks to be the same carb. his has a different neck on it.  Mine is straight where his has a flare on it.  His originally had the oil bath air cleaner.  I could rebuild that carb and redo that cleaner but I was wondering about the filter inside the oil bath cleaner.  Can you replace it and how?  The only thing is I do think the oil bath cleaner is cool and everything but I don't know how much I really want it on my truck though.  I have a couple styles of air cleaners but none of them work with my original 239 carb.

I will get pictures up as soon as I can.

But I am begining to think if even if the air cleaner my be a problem I might go through the trouble of switching the distributor gear and put my other intake on.  Because if by doing that will make linking throttle, air cleaner, carb choice, ect easier to accomplish I might actually go through with that option.  Because to be honest it wouldn't be to hard of a change.  I will have to repaint my other intake the yellow like my motor (right now it is Ford Blue).  That is just a minor set back though.

Any suggestions?

Thank you very much everyone!
