4v intake manifold id
I've got this 4 barrel FE intake manifold sitting in the garage and I have no idea what it is.
C7AE-9425-E is the part number cast on it.
I know the C7AE-9425 ids it as a 67 4v manifold, but I'm not sure about the E, and what it says about it. Any help would be appreciated.
Also, looks like there is a 7-13 on it (I believe that's the casting date, but I'm not sure), a larger S shaped letter cast on it, and "DIF" cast on it.

Pretty much std issue FE iron 67-68. This has the smaller intake ports for the mid 66 and later FE heads. Date code should have a letter between those numbers 7-13. 7 is the year 67, letter A-M Jan-Dec skipping the letter "I" is the month. A= Jan, B= Feb and so on. The "I" was easily confused for the number 1 so it was dropped and not used. 13th day of the month it was cast. DIF is for Dearborn Iron Foundry. There are both "S" and "T" intakes. S intakes were the car version and T the truck. But both have been found in opposite applications. Both are more or less the same casting. The "E" at the end is the level of revisions. So 5th revsion or change of some sort along the way. It's also nice and heavy.

Glenn to the rescue! LOL
I searched the net54 site: Someone said the C7 intake used the more common small thermostat, while my C6 intake should use the large thermostat. Is that fact or crap? Now I'm wondering because I don't remember having any problems buying a thermostat for mine.

For date cast look for 2 round headed marks with 3 or 4 digits inside them
ie: *7L22*

I am looking at the same intake mani here... C7AE-9425-E Mine is date code June 13, 67 and is from a 67 Mercury Marauder FE 410 CID. The 410 is a 428 crank in a 390 block only used iin Mercs 66 and 67. I have this one now bolted to a '65 352CID FE and with the ford 4V the results are excellent. This intake also has the large "S" on a runner .. the same intake was used on 427 FE's in the latter sixties as well.
hope this helps.
