Carb adapter

Does anyone know where I can get an adapter to put a holley square bore to factory amc 4 barrel manifold? A spread bore adapter doesn't work. The primaries are to close together.

Thanks,

John

 

Apparently they exist - not sure that they are made any more. There's a picture of one at the bottom of this thread. http://www.ifsja.org/forums/vb/showthread.php?t=97786&highlight=spread+bore+adapter

You need an adapter for the Motorcraft 4350 to a Holley square pattern.

I think it will be easier to find an AMC square-pattern 4V manifold and swap manifolds. IIRC 1975 and earlier is square pattern.

 

Thanks. Due to that post having the part number, I found some of them. Summit racing had 9 in their ebay store. They sure are proud of them though. They are $62 ea.

Advance auto has them for $40, I am looking for the same thing. I am going to check with autozone, most of the adapters are $20 except for the one I need.

 

I don't see a part number there.

Please post a link to the Summit part.

If you are referring to this http://www.jegs.com/i/Edelbrock/350/2732/10002/-1 I don't think it will work. The bolt pattern looks the same, but the web between the spread bores is very thick, and I think it will interfere with the square bore secondary throttle plates.

I was talking about the part number in the post you put a link to. TD-2199.

Thanks again.
