Ford Casting Identification

In your other thread the code you posted, that you found behind the starter 4E22 is the date code the block was cast at the foundry, May 22, 19x4. Close by that code, you should see a larger code that is in cast also; something like this............... E4ZE-6015-A. Here is how the code breaks down:

The first digit indicates decade. In this particular case the "E" indicates 1980's.

The second digit indicates year of decade. In this case 1984. (those first 2 digits will tell the year of the block)

The third digit indicates the car line the block came from. "Z"=mustang, "T"=Ford truck, S=Thunderbird, "D"=Falcon, etc.

The fourth digit "E" indicates "engine group" or engineering group".

"6015" four digit number indicates basic part number ...... (cylinder block.)
"9510" is carburetors, and so on.

The suffix letter "A" at the end of the part indicates an original part. If Ford revised the part one time, then the part would carry the letter "B" instead of the letter "A". A second revision on the part would carry the letter "C", third revision the letter "D", and so on.

In the 70's Ford sometimes used double letters like AA,AB, and so on in their cylinder head castings as a learning curve with emissions.

You can even tell what plant the block came from. "DIF" indicates Dearborn Iron Foundry. "WF" or "WIF" indicates Windsor Iron Foundry. A "C" circled around an "F" indicates the Cleveland Iron Foundry.

Date codes can be found 2 ways in Ford castings. When the four character date code is cast into the piece, this indicates when it was cast at the foundry. When it is stamped into the piece, this indicates the date of manufacture.
