Help identifying 4v FE intake

I'm looking at a 4 bbl cast iron intake manifold that I'm told was taken off a 390 out of a 65 car. The part number cast into the top is C5AE-9425-C. Can anyone tell me about it? Would it be a good match for my 69 360 FE (currently with 2 bbl intake)?

See https://www.ford-trucks.com/dcforum/DCForumID7/57.html

This manifold has the tall ports and I am assuming your ’69 360 heads have the shorter ports. There would be a mismatch with the head acting as a dam on the bottom of the manifold runner. Not a good thing but Ford recommended the CJ manifolds on the GT’s even though they have the same mismatch problem.

I think you would be much better off with any of the “S” intakes with your heads imo.

Thanks. That's exactly what I was looking for. Frankly, I don't know what size ports I have, as I've never had my existing manifold or heads off, and I don't know for sure whether they are original.

Hey Barry, I have one with #C8OE-9425-C that appears to be cast with a spread-bore carb in mind but is machined for Holley. Do you know what's up with that?

They are all like that. Don’t know the story but it is one of a few small differences between the CJ and the so-called identical PI unit. Maybe they planned on a spreadbore version like the 429CJ?

I have an intake that I bet you haven't seen many of. It is a 4v FE ,identical to the picture of barry's, with one exeption, mine has a freeze plug in it. yep it is right under the heater hose neck. I am not sure but I think the casting is of a 63'

That "freeze plug" opening was used for an oil filer/breather tube before emission rule dictated PCV valves etc.
