What Is a “K-Code” Mustang?Last Updated February 5, 2020
If you are one of those fortunate individuals who have a classic Mustang from the early years in your garage, it’s quite possible you are the proud owner of a Mustang equipped with a “K-Code” engine. The “K” signifies the engine code that was part of the vehicle identification number.
First offered with Ford’s Comet and Fairlane models in 1963, the K-Code was actually a 289-cubic-inch high-performance V-8 engine that was also referred to as “Hi-Po” and delivered a power output of 271 hp. This represented a significant power boost over the standard 260-cubic-inch, 210 hp “D-Code” engine available at the time.
Available With the 1964.5 Mustang
The K-Code engine was first made available to Mustang buyers in June of 1964, about two months after the original 1964.5 model (which was technically a 1965 Mustang) was unveiled. In addition to the upgraded engine, buyers who chose the K-Code option also received a special handling package and dual red-stripe tires.
Ford marketed the K-Code engine as a way for Mustang owners to enjoy a sports car performance that matched the Mustang’s sports car styling. Ford also suggested the K-Code would appeal to buyers who were interested in participating in competitive events such as rallies and gymkhanas.
Three-Year Production Run
Less than one percent of the approximately 1.7 million Mustangs produced during its first three years of existence were actually equipped with a K-Code engine, and Ford did not offer the K-Code after 1967. The K-Code, however, did help pave the way for more robust Mustang engines of the future, such as the Cobra Jet and Boss. The relative scarcity, combined with its legacy as the first truly high-performance engine available with the Mustang, makes a K-Code Mustang a highly sought-after vehicle by classic car collectors.

Improving your Mustang’s gas mileage is a dilemma that many enthusiasts struggle with when thinking about their muscle cars; they want to put their high-powered engines to the test, but they don’t want to make routine trips to the gas station every time they put the pedal to the floor.
Some of the most simple and overlooked questions can be the hardest to find an answer to. One of those would be the simple question of what does GT stand for when us enthusiasts use the term Mustang GT? Yes, in the most general sense, it stands for Gran Touring, but for the Mustang it means so much more.
They say that you should never judge a book by its cover, and this especially rings true for the EcoBoost engine. What it lacks in size, the EcoBoost more than makes up for it with its power and efficiency capabilities. Thanks to its turbocharged, direct-injection technology, the EcoBoost squeezes every ounce of power out of the smaller motor to create a one-of-a-kind driving experience. If you have ruled out a V8 engine, an EcoBoost motor would be an excellent choice for your Ford Mustang or F-150!
