I have a 239cid OHV Y block and I want to put my 2bbl Holley in place of the original 2bbl bottle neck.  I don't know exactly what size they both are, here's a picture of the one I want on this motor in the end.

I have the intake for that carburetor but it was from the 272 Y block and I noticed that that intake is different than the one from the 239.  So I am looking for an adaptor plate to go from the 3 stud bottle neck carb. to the 4 stud Holley.  I have spent a couple hours looking for one but I have been unsucessful.  Does anyone know if someone makes one.

I should also ask would it be fine running the 239 with the Holley?

Thank You.

Have not seen one of those in decades. Why not just get a 57-62 2bl intake manifold and bolt it on?  Have you noticed the linkage is on different sides on these carbs?

Goodluck,

Ron.

Looks like you can do it with a combination of the "late carburetor adapter" and "Holley 2 barrel carburetor adapter."

The newer intake will have larger ports and make it difficult to keep the intake sealed.

I adapted a late 2 barrel to my flathead 3 bolt manifold.  Here in the midwest the lack of manifold heat transfer to the carb base caused me no end of aggravation in cool and cold weather.  I didn't see any gains anyway, the manifold was as big a restriction to air flow as the original carb.

I have the intake for the carb. pictured above the problem I seen with it was that the intake ports are 1/8" inch bigger on the intake than on the heads.  With that intake I could bolt up my original linkages but I just thought there would be a problem the ports being so different in size.  I did notice that the linkage mounts are on opposite sides of the intake as that of the Holley 2bl.  Thanks

I will check that link out.  I did notice the difference in the size and that is why I stuck with the original 239 intake instead of my 272 intake for the 2 bl Holley.  If nothing else I might have to live with the stock 239 2bl.  I just wanted to put the 2bl Holley on because it has already been rebuilt and I have a new chrome Holley air cleaner to go on it.  Plus the 239 carb hasn't been rebuilt yet.  Thanks

To be honest I am not really looking for the performance end of my truck.  I will be driving this truck so slow and easy it will be remarkable a person could drive so slow Hahaha (this is probably the only time you will hear that from a 22 year old ).  I actually down graded the truck from a 272 to the 239 but not on purpose, but to me it won't matter anyways.

That is still nice to know though that it won't make much of a difference.  I just thought I could save some money by not having to get the 2 bl bottle neck carb rebuilt but if I have to get new linkages anyways I might just have the bottle neck rebuilt if it makes linkaging a little easier.  Thanks

if intake is 1/8" bigger than ports that'll work.

you can use mopar style throttle cable to

hook up throttle.

carb will work fine, long as you're in the ballpark.

DON'T toss original intake & carb, put it on shelf.

I will never throw any parts I have duplicates and triplicates of so many parts and I will even have a hard time selling those much less throwing them away. I guess I will have to look at if which gasket will work best 239 or 272. The only thing is I guess I already have the 239 intake already painted.

So I take it that there is not an adaptor out on the market that will work. If so I might actually see if I can CNC machine one at my work. I can also model it up with the 3D CAD software to see what it will look like. That way I might actually be able to reuse my original linkaging. But I might still have to think of something to do to bolt it to and manifold. I will have to do some research or decision making yet.

Have you checked on the ones I linked?



A custom adapter will work, too but I don't think the adapter alone will solve linkage issues. If you were to turn the new 2 barrel around to get the new linkage on the correct side, I do believe that the linkage will now have to push it open rather than pull. I'd just leave the new 2v in it's standard orientation and make new linkage to hook it up.



I'm really surprised there is not a specific adapter for this. There seems to be for just about everything else, other 2 barrels, 1 barrels.

Here are a few pictures.  The carb. is the one for the 239 intake (the one that I want to eliminate).  And the intake is the 239 intake that is on my motor right now.

  

I tried your link and I didn't see an adaptor that looked like what I am looking for.

Ok I just found this thread in a search and was wondering what the relationship is between the 3 bolt carb and the distributor.  I knew that the distributor is different in this engine I think there is like 13 teeth where the 272 had 14 teeth something like that but.  What would be the issue with going away from the 3 bolt carb. anyone?  Thanks
