Cleveland small-block: The Ford 335 small-block family introduced in 1969, was referred to as the “Cleveland” engine, due to the fact that they were built in the Cleveland engine plant. They came in 351 cubic-inch and 400 cubic-inch variants, and were known for their large port and valve sizes, and remained in production until 1982. However, it was a placeholder in the Mustang while Ford meanwhile finished prepping a more performance-oriented engine family, known by the internal code “335.” This would become the 351 Cleveland, named for where it was produced: Ford Engine Plant Number 2 in Cleveland. Cleveland engine characteristics. The thermostat housing is on the block extension which contains the timing chain; deck height makes a 351c intake not fit on a 400, Spacer plates are available to use a 351C intake on a 351M/400, but it's more practical to use these mainly for large port intakes on 400s using 351C 4V heads.

Model A Ford Assembly Plants and Body Numbers
by Dave Sturges
Glenwood, Maryland
I have undertaken a research project to identify the Model A Ford Assembly Plants and their corresponding ID number codes that were stamped onto the bodies of some Model A’s.
This Assembly Plant ID number is different from the engine serial number, different from the Ford Body style number, and different from the body company style number. This study specifically concerns the ID number stamped onto the body at the Ford assembly plant by Ford workers.
Location of the Assembly Plant ID Number
The body assembly plant number was stamped into the top of the horizontal front body cross member, into the body side rails on the floor board level, or into the wooden cross member on certain body styles such as Cabriolets and Fordors.
The number can be located anywhere on the cross member and can be oriented to read from driver to passenger side, from passenger to driver side, or from back to front. Also, the size of the stamp used differs from one assembly plant to another.
Briggs and Murray bodied cars also had a body company number tag affixed to either the wooden body cross member or firewall. I am not collecting these tag numbers. Body company tag number information can also be found on the MAFCA website.
Most, but not all, of these numbers contain from one to five letters that denote the specific assembly plant where the car was assembled. The digital portion of the number could indicate body style production. To date, 31 of the 35 assembly plants have been equated to their letter codes.
It would appear that each of the assembly plants, regardless of its particular capability (i.e., major, standard, or minor assembly plant), stamped these numbers into the body cross member or body side rails.
For some unknown reason, not all Model A cars have an assembly plant ID number, but that could largely be a result of the body cross member or side rails being replaced or the assembly plant number being filled in during restoration.
Model A Ford Assembly Plants – US
Following is a list of the assembly plants with their equated letter codes.
Letter Symbol | Location | |
---|---|---|
1. | A | Atlanta, Georgia (the star is sometimes stamped at the end) AA also noted |
2. | BO | Buffalo, New York |
3. | CE | Charlotte, North Carolina |
4. | CR | Chester, Pennsylvania |

8. | G | Columbus, Ohio |
9. | DS | Dallas, Texas |
10. | DR | Denver, Colorado |
11. | DM | Des Moines, Iowa |
12. | E | Edgewater, New Jersey – Opened Nov 15, 1930 and replaced Kearny, NJ. |
13. | H | Houston, Texas |

15. | JE | Jacksonville, Florida |
16. | Kansas City Missouri (possibly used letters ‘AF’) | |
17. | KY | Kearny, New Jersey |
18. | LA | Long Beach, California – Opened June 1930 and replaced Los Angeles. |
Used LA through at least August 1931 | ||
19. | LA | Los Angeles, California (the month and year appear as part of the number) |
20. | LE | Louisville, Kentucky (the month and year appear at the end of the number) |
21. | MEM | Memphis, Tennessee (Sometimes has ‘AX’ preceding the number) |
22. | Milwaukee, Wisconsin | |
23. | NO | New Orleans, Louisiana (the number ‘2’ precedes the “NO”) |
24. | NK | Norfolk, Virginia |
25. | OC | Oklahoma City, Oklahoma |
26. | Omaha, Nebraska – Possibly used ‘AU’ | |
27. | Pittsburgh, Pennsylvania | |
28. | PO | Portland, Oregon |
29. | R | Richmond, California – Opened in August 1931 and replaced San Francisco |
30. | F | Detroit (Rouge), Michigan |
31. | SFA | San Francisco, California (SFAA) has also been used |
32. | AS | Seattle, Washington |
33. | S | Somerville, Massachusetts (also used letters S-S, SAXC, SAX and SSAX) |
34. | STL | St. Louis, Missouri (has AX preceding the STL) |
35. | TC | Twin City, St. Paul, Minnesota |
Note that most of the letter codes are from one to five letters and there is a systematic way most of the letters were derived from the city location of the assembly plant. When assembly plant location cities have a single word, the letter code is generally the first and last letters (i.e. Buffalo – BO, Charlotte – CE, Chester – CR, etc.)
Assembly plant locations having two words generally use the initial letter from each word (i.e. New Orleans – NO, Oklahoma City – OC, Twin City – TC and so forth).
It is difficult to differentiate the stamp used to represent the letter O from the stamp used for the zero, and this presents a problem for some of the body assembly plant letter codes.
Anyone having a Model A with a number containing letter codes listed above can determine the origin of that car body and possibly its final assembly, while others will have to wait for more numbers to be collected.
The following additional letter codes have been noted but are not yet equated to their assembly plant: AEX, AXC, DO, T, W, 3S, and 5S.
Model A Ford Assembly Plants – Canada
Following is a list of the assembly plants with their equated letter codes.
Letter Symbol | Location | |
---|---|---|
1. | M | Montreal, Quebec — 119-139 Laurier Avenue East |
2 | T | Toronto, Ontario — 2951-2991 Danforth Avenue |
3 | W | Winnipeg, Manitoba — Portage and Wall Streets |
4 | V | Vancouver, British Columbia — 1160 Hamilton Street |
Most, but not all, of the cars having the ‘F’ code compiled to date are 1928 or 1929 Tudors. The numbers following the letter assembly code increase when the cars are put in month and year order.
The following is a list of 1928 and 1929 Tudors with the ‘F’ letter code in production date order.
Assembly Plant # | Production Date | Current Location |
---|---|---|
F1334 | 2/28 | Ohio |
F5065 | 2/28 | Ontario |
F7368 | 7/28 | New Jersey |
F16307 | -/28 | Michigan |
F41967 | 10/28 | Ohio |
F42469 | 11/28 | Michigan |
F56571 | 1/29 | Maryland |
F75541 | 3/29 | Michigan |
F78541 | 3/29 | Michigan |
F83633 | 4/29 | Pennsylvania |
F83683 | 4/29 | Vermont |
F88948 | 5/29 | Alabama |
Some ‘F’ bodies were assembled outside of the U.S. and have Canadian engine numbers. In fact there is almost equal mix of U.S. and Canadian assembled cars with ‘F’ series assembly plant numbers.
The ‘F’ series system was modified in late 1929. On these cars the letter F is preceded by a number, indicating the body style. Below is a listing of the numbers compiled to date equated to their body style.
Prefix | Body Style | Ford Body Code |
---|---|---|
1F | Standard Coupe | 45A, B |
2F | Sport Coupe | 50A, B |
3F | Standard Fordor | 165C |
4F | Tudor | 55A, B |
5F | Town Sedan | 155C |
6F | Phaeton | 35A, B; 180A |
7F | Roadster | 40A, B |
8F | Roadster | 40A, B |
9F | Open Cab Pickup | 76A, B |
11F | Deluxe Roadster | 40A, B |
12F | Closed Cab Pickup | 82A, B |
15F | S/W Fordor | |
16F | Town Sedan | 155A, B, C, D; 160B |
It is very interesting to note that all cars noted to date with letter code of ‘D’ or ‘DO” are 1928 or 1929 Coupe bodies (i.e. Standard, Special, Business or Sport Coupes).
Summary
I would like to collect additional body assembly plant numbers from as many cars as possible. In addition to the body assembly plant number, please forward as much of the following data as possible:
- General location of the number on the cross member or side rail
- Orientation of the number (does it read from the drivers side to passenger side or vice-versa)
- Date on firewall for years 1928 and 1929
- Frame, engine number, or both if different
- Month and year
- Body style
- Current location of the car
- Original owner location of car, if known
It only takes a few minutes to locate the body assembly plant number, if there is one to be found. Just lift the front floor mat or carpet and look on the top of the front body cross member in front of the seat riser or support or on either side rail. The only assembly plants known to stamp assembly plant number on the side rail is Denver.
Further, I would like to correspond with anyone having additional information or specific knowledge regarding which assembly plants were classified as major, standard, or minor, and when or why the body assembly plant numbers may have been stamped into the body.
It’s about time we solved these numbers for the Model A community. A good number of Model A owners have expressed an interest in tracing the history of their cars, and an assembly plant number will provide them with a starting point.

The 1971 Mustang VIN Decoder is a great tool for Mustang restoration and identification, when searching for your perfect pony car.
Its handy when trying to find out whether or not you have a true 'numbers matching car', meaning that your vehicle has, if not the original parts that came with the car when it was manufactured, at least pieces that would have been made when your car rolled off the assembly line.
You can use it to identify and verify the year, model and engine choice in your vehicle, which can then be checked against the parts now on the car. Your Vehicle Identification Number or VIN can be found by looking through the lower portion of the windshield on the drivers side of the car. It is a small metal plate that's stamped with alpha numerical codes.
And it is those numerical and alphabetical codes which allow you to decode exactly what equipment was on the car at the time of manufacture and even where in the country or world it was shipped to for delivery to the local Ford dealership.
Example Vehicle Identification Number
In the example above, our serial number is: 1FO5M149901
Using the 1971 Mustang VIN decoder, the first number from the left (1) IS the last digit of the year your Ford Mustang was manufactured (1971).
The second position (F) tells us that the assembly plant was Dearborn Michigan.
The third and fourth positions (05) denote a Mach 1
And the fifth position (M) tells you that you would have a 351 cubic inch V8 engine (Cobra Jet) with a 4 barrel carburetor which produced 280 horsepower.

Comparison With Parts On The Car
Here's where the rubber meets the road. Use the information provided by the 1971 Mustang VIN decoder and make a list of the standard equipment listed. Then you can one by one find the parts and verify that they are or are not the correct ones for your car.
For example, when I found my 1970 Mustang fastback, it came with an engine. From the data plate and VIN codes I was supposed to have a 302 cubic inch engine and sure enough the block was stamped '302' so I did indeed have the right size motor. Looking closely at the stamping or casting numbers on the block, however, it turned out that it was a 1968 block.
Great for a daily or weekend driver, but if I wanted a numbers matching car suitable for shows and judging, I would need to find one that was produced for the 1970 Ford model year and one that was offered in that car. Ford made a number of different engines whose specifications differed slightly depending on the application and that can be an issue.

351 Cleveland Serial Number Location
And in the case of a 1971 Mustang, VIN decoder information can specify a 351 cubic inch Cleveland engine, but two standard Cleveland engines were available, a 2 barrel model and a 4 barrel carburetor model which had entirely different cylinder heads, intake manifolds and of course carburetors.

Good things to know. So use these codes to first identify what you should have and then check the parts against their casting numbers to verify exactly what you do have.
