Ron welcome to FTE, I don't know much about your Y-block intake but I'm sure someone will be along who does. Sounds like you have a full plate with 2 F-100s. Try to post some pictures of your trucks cause we do like to look at pictures.

Are you sure it isn't 9425-A? I only know of an A and a B manifold. A had a small base 4 bbl for what is commonly called a Holley Teapot carb, while the B manifold came along in 1957 (I think) and will fit modern sized carbs. You would need an adapter to run a modern 4bbl on the A manifold.
There is also a site called "Y Blocks Forever," and they have forums specific to the Ys. I can't imagine replacing anything "modern" with a Y, though. Sounds like you have a good one. There isn't a McCulloch supercharger on it, by chance is there?
