Deciphering Your Ford Engine's ID Tag

  

All Ford engines built from early Jan. '64-up include an engine identification tag. This tag describes CID (cubic inch displacement), model year, year and month of production (the letter 'I' was not used to prevent confusing it with the number '1'), and the change level number.

The location of this tag is as follows:

  • Under coil attaching bolts on all 6-cyl. and most standard V-8 engines
  • Under the dipstick-tube attaching bolt on 8-cyl 352 engines
  • Under the heat indicator bulb on 8-cyl. 330, 361, 391 engines
  • Under the carburetor attaching stud on 8-cyl. 401, 477, 534 engines

The Ford Master Parts catalog uses the change level number in the same manner that the date restriction information is presently used. The change level number is advanced only when a replacing part (or assembly) being introduced and the old part (or assembly) it replaces are not completely interchangeable.

NOTE: When I began to construct this page, it was for my own personal use and I used notes and documentation from several sources, none of which was documented in my notes. One source listed some of the early years, while another source neglected to mention any year. Therefore, details mentioned in the 'Notes' section might be applicable to other years. In other words, when details are listed for some years and not others for the same I.D. number listed, those details might be applicable for other years not specifically mentioned, but I can't verify that. This page is incomplete, in terms of details, and some existing ID numbers aren't even listed, but I will edit this page whenever new information becomes available.

For the most-accurate listing as published by Ford in the Master Parts catalog, see:
 1965-1972 Ford Car Engine Identification Tag Codes

F-2 = Ford 2-bbl
F-4 = Ford 4-bbl
H-4 = Holley 4-bbl
H-8 = dual Holley 4-bbl		 A/T = automatic transmission
M/T = manual transmission
