A Numeric Engine Code on a Mustang?
Have you ever seen a classic Mustang VIN number that had a numeric engine code? Me either! Myself and a few other knowledgeable people would instantly say that it's incorrect or had been stamped incorrectly at some point; but its true...
Lets take a look at the well known and accepted standard VIN for a classic Mustang and break it down:
The Mustang VIN number has a letter within it that identifies the engine that was installed in the car; take for instance the vehicle Identification Number for Project Playboy: Project Playboys VIN: 7R01C186352
| 7 | R | 01 | C | 186352 |
| Model Year | Production Plant | Body Style | Engine Size | Production Unit |
| 1967 | San Jose, CA | Coupe | 289 2v V8 | 186352 |
All of the engine codes for classic Mustangs are designated by a letter as seen below for the 1965 Mustang model year:
1965 Mustang Engine Codes
| Code | Engine |
| A | 289-4v |
| C | 289-2v |
| D | 289-4v |
| F | 260-2v |
| K | 289-4v Hi-Performance |
| T | 200-1v |
| U | 170-1v |
The Numeric Engine Code Mystery
I am working with a client located in Ecuador on his project and requested the VIN number so I could properly identify the engine in his 1965 Mustang, he promptly emailed it over to me for review; you guessed it, it had a number in the position of the engine code.
I was a little confused and figured that the VIN was not completely readable or somebody had re-stamped the VIN on the vehicle down in Ecuador, so I requested a photo of the VIN so I could verify the quality of the stamping and the location. I then received the photo and there in the photo clear as day was a ford VIN with a numeral for the engine code.
Mystery Solved
Once I had solid evidence of the VIN number with its numeric engine code I knew I had a pretty good chance to solve the mystery. I sent the photo of the VIN to Marti Auto Works; they responded and said it is legitimate and correct, the numeric code designation was for a low compression export engine.
I also managed to round up a list of Ford Export Division Engine Codes
