It's the 5th digit of the VIN. It tells which engine was factory in that car. T is 200ci I6, C is 2bb1 289, A is 4bb1 289, K is 289 HiPo, F is 2bbl 302, J is 4bbl 302, Q & R are Ramair & non-RA 428CJ/SCJ, S is 390, X is 390 2bbl (68 only). There are more, but this is all off the top of my head.

The squirrels in my head have spoken.

The "code" usually mentioned is the engine code letter from the factory that's put in your VIN. "K" for instance, stands for the higher performance 271hp 289 4bbl. in the early cars. As the years went by and engine sizes and equipment changed, so did the code letter.
Its the 5th letter in the number of vintage Mustangs, by the way.
