The C6 AE would indicate that it is an intake originally intended for a Big Ford( Galaxies at the time). The 428CJ's have an "O" where the A is in this intake indicating it was originally intended for Fairlanes. From the casting number It would be either a 352/390/428 intake(cast iron),428 PI intake or single carb 427 if aluminum.
As someone mentioned earlier, there is a "G" intake and I have seen some poorly cast letters over the years. Is there any possibilty that is a G instead of a C? A pic would resolve any questions, so until then we are all just speculating on an intake that may be worth scrap value. If it's cast iron, the shipping to the next county would probably cost more than it's value.

Here's what I have with "AX" and "O" for FE's:
C7ZX-A = 1967 GT500, aluminum dual plane, dual 4V carbs
C8AX-A = 427-8V, medium riser, racing
C8AX-B = 427-4V, tunnel port, racing
C8OX-A or C = 1968 GT350, aluminum dual-plane
C8OE-C = '68-'70 428 CJ, SCJ, GT500; cast iron; GT500KR, 69-70 GT500

As I recall, anything with an "X" and many with a "Z" were part of the "Muscle Parts" program back in the day. I do have the original '68 Muscle Parts catalog along with several other Ford publications from those days. If anyone needs something looked up, just let me know...

Is the intake cast iron, aluminum, or magnesium?

Is it a Low Riser, Medium Riser, High Riser, or Tunnel Port?

If the intake is an NOS magnesium then $$$$, if it is a crusty iron intake, then it is not worth shipping. Of course, aluminum is somewhere in between.

It's cast iron - I do know that. As far as other details, I don't know. I gotta have my bro-in-law E-mail some photos if he can get them to me. He said the intake & carb were on his old drag boat many years ago - a 427.

This is a long shot but the drag boat wasn't a 427 hemi was it? There were a few drag boats fitted with a Ford 427 Hemi (pushrod hemi, not a SOHC). Mickey Thompson made the heads from Chrysler hemi heads to fit 427 FE.

I ,too, have those as well as each progressing Ford performance group(OHO,SVO,etc.). There is a difference between part # and casting #. You will find ,very often, that there may be more than a single casting number for any given part #.

That would have been aluminum and probably without a Ford #. The fact that he knows it is a cast iron intake indicates it is a bread and butter intake manifold. There was NO factory 427 Intake that was cast iron and any marine engine would have had a J code instead of an A. I would venture that unless someone is needing a casting # correct intake for a restoration and has to have a specific date code( which isn't known), I'd say it's maybe a $50 intake. IF it has a date code that can't be found in the 100,000 produced and laying around it may be worth more...to someone. Shipping around the corner on that would cost more than $50. If it had been stated in the OP that it was cast iron the thread would have ended in maybe 4-5 posts.

Then perhaps the "C" code is a mis-read or poorly casted "G" code as earlier mentioned. The "G" is a run-o-the-mill cast iron 390/428 intake. It would be fine on a 66 or 67 galaxie restoration. It's poop for performance though.
