I think the actual part number is 9425-B, might make searching easier.

Tealy, email sent.  Did you rreceive it?

The part number is ECZ-9425-B for the '57 cast iron 4V intake manifold.  This is the best of the cast iron intakes for the Ford Y.  The 9425-B number is used in many of Ford's other engine families for their intake manifolds.  Joe-JDC

Sounds like something Ford would do!

Joe is correct regarding 9425 being used by Ford to identify part as an intake manifold, but not necessarily a Y-block manifold. 

Joe, in your 2nd photo of the bare manifold, there is an indentation/recess in the lower-right corner of the photo. Although I've seen a number of photos of intakes/w plenum opened up to two ovals (Ted said he routinely does it), this is the first one I've seen with that indentation/recess. What is its purpose? 

Thanks

If I understand your question; by the look of it, the lower passage front pair is fed from the top opening in the manifold and it saves cast iron. It’s the reverse on the rear of the manifold which I think you are inquiring.

I'm referring to the notch/recess/indentation at the lower-rear edge of the carburetor mounting surface. Maybe there was a clearance issue with the distributor. 

I got it. The recess is an integral part of the intake manifold casting. Maybe it's the light/angle, but it looks different in JDC's photo. I went back and looked at Richard's photo of his modified 57 intake for comparison purposes. The paint helps to distinguish the plenum's carburetor mounting surface from the runners. You'll have to back a few months in Classifieds to find Richard's intake.

Same intake manifold after porting and painting.  Joe-JDC

Wanna trade? Just kidding, but I do intend to have mine done. Years ago, my machinist friend opened up the plenum of my 289 manifold, and I gasket-matched the runners. Hopefully, paying to have my Y intake done will be cheaper than Mummert's aluminum intake; otherwise, I'll sell mine and buy Mummert's. My only concern is limited hood clearance on my 55 Tbird. According to John's description, his Tbird intake is still a bit taller than my 57 intake. A dropped air cleaner  is necessary when using a carb spacer.
