Engine Block Serial Number Lookup
Aug 11, 2017 How to Identify a Ford Motor. Engine Code Number. My 1976 Ford truck has a manufacture number on the block on a tag with the numbers y50805 on it.
Please Note: This info is incomplete and I am still trying to compile this list. I am trying to gather information on decoding engine serial number identification prefixes (pre-1954) and suffixes (1954 - 1959) to add to this site. If you have any info that can be added, please let me know.

Ford Part Numbers, Casting Numbers, and Date Codes Ford Part Numbers, Casting Numbers, and Date Codes Decode Ford, Lincoln, and Mercury part numbers, casting numbers, engineering and service parts, and date codes Ford kept track of the various parts and castings in its inventory by assigning each item its own unique alphanumeric identification number. These numbers provide a lot of information to those who are familiar with what the numbers mean. The unique identifier is a series of numbers and letters that are put in a specific sequence, and the location of the digit determines what that digit designates. Information commonly provided by part numbers includes the decade during which the part was designed or manufactured, the year of the decade the part was designed or manufactured, the car line the part was originally designed for, the engineering department originally responsible for the design, the basic part number, and the changes made to the original design. What can be confusing about these numbers is that a part designed for one year might actually be used for several years, or a part designed for one car line might be used on other lines as well. For instance, a part originally designed for a 1964 Ford could often be found on a 1964 or 1965 model Thunderbird, Mercury, or Lincoln as well. It is actually quite common to find parts originally designed for Thunderbirds on Lincolns, and Falcon parts on Mustangs.
In order to spread out the costs of designing and manufacturing a part, Ford used parts on different models. The Ford part number on the box shown at left is on the top line: B8A-9431-A. Other information indicates it was an Engine Engineering Division design, weighs 9 pounds, provides information on the quality control inspection, and the date packed. A typical Ford part number looks like this: C5SZ-1005-A Here's how this number is decoded: C = Decade of design (1960's) 5 = Year of decade (1965) S = Car line (Thunderbird) Z = Engineering Department (Ford Service Parts) 1007 = Basic part number (Wheel Assembly) A = Design change (original design, no revision) This basic wheel was used on Thunderbirds from 1965-1967. While it was possible to use a wheel from a 1964 Thunderbird on the rear of a 1965 Thunderbird, that wheel would not fit on the front wheels, and as such was unacceptable for use as a spare tire. In 1968, the Thunderbird received a new front disc brake design, and with it a new wheel, listed at right. A similar Ford part number looks like this: C8AZ-1007-E C = Decade of design (1960's) 8 = Year of the decade (1968) A = Car line (Ford) 1007 = Basic part number (Wheel Assembly) E = Design change (4th revision, not including original design) Note that this wheel assembly is no longer a Thunderbird design, but was initiated for Ford vehicles.
The size, hole, and bolt circle are all the same, but this particular wheel has additional identification markings with a 'V' stamped into the metal and yellow paint to designate its offset. EXAMPLE PART Let's break down the Ford part number on the box shown at left: C8SZ-7A247-A C = 1960's 8 = 1968 S = Thunderbird Z = Ford Division Service Part 7A247 = Basic part number for Switch - Transmission Control Selector Neutral A = Original design (no revisions) It should be noted that the SW-653 number also identifies this part correctly, and is an additional reference number used by Ford and its suppliers.
It is also a unique number, and changes due to specific equipment options on a given vehicle. According to the parts book, this switch fits a 1968 Ford Thunderbird with tilt steering wheel. There were multiple revisions to this switch, so there is a notation that I.D. Markings E, F, G or H as the suffix digit at the end of the part number are also applicable. This could mean revisions to the part or multiple manufacturers supplying the part to Ford.

Another part is provided for 1968 Ford Thunderbirds with fixed steering wheels, and it is C8MY-7A247-A (SW-649) with revision I.D. Markings of F, G, H, J or K. Note that this switch was originally designed for the Mercury Division, due to the 'M' as the third digit in the part number. This indicates the part was originally designed for a 1968 Mercury, and illustrates how parts crossed over from one line to another, across divisions, and the equipment provided on a particular vehicle often determined that different parts were used. In order, here is what each digit in a Ford part or casting number represents: DIGIT #1—DECADE OF MANUFACTURE: A - 1940 B - 1950 C - 1960 D - 1970 E - 1980 F - 1990 G - 2000 DIGIT #2—YEAR OF THE DECADE: 0 - 1960, 1970, etc.
1 - 1961, 1971, etc. 2 - 1962, 1972, etc. Example: B8 = 1958; C1 = 1961; C9 = 1969; D9 = 1979, etc.
