The number refers to the cubic inches of displacement, which is the volume swept by all the pistons in the engine. This number is directly linked to the amount of horsepower the engine can provide, but many variables determine the horsepower of an engine, including efficiency, design, and fuel delivery method.

Normally, more expensive, larger engines have more horsepower, but this is not always the case. As far as raw power goes, these two cousin engines are surprisingly divergent. The larger put out up to horsepower stock on the year of its introduction, while the only cranked on As the years wore on, both engines decreased in horsepower, coming down to about horsepower by Both engines were part of the Ford family, which was named for the 3.

It was finally discontinued due to demands for a more efficient engine to respond to the newly environmentally aware consumers. This is where most of the difference between the engines is made up. Thewith less displacement volume, had a shorter stroke length of 3. The longer stroke produces more power and also allows for more and better high-performance modifications.

So Ford engineers developed a unique set of heads and placed them on a Mustang in This Mustang was called the Boss The head design was also used on a special Mustang. That car was named the Boss Ford sold enough Boss Mustangs to qualify the motor for racing.

After much consideration, it was decided by Ford that the Mustang would be the car that would house this new engine. The Boss engine evolved from the Ford engine. It used four-bolt main caps, a forged steel crank and forged steel connecting rods. The engine featured aluminum cylinder heads, with a semi-hemispherical type combustion chamber which Ford called the "crescent".

These heads used the "dry-deck" method, meaning the coolant circuit for the block was separate from the cooling circuit for the head The "dry-deck" method of design is intended to strengthen the block by removing the open coolant jackets around the cylinder and reduce hot spots by providing more direct cooling.

Each cylinder, oil passage and water passage had an individual "O" ring style seal to seal it tight. Although a head gasket is used, it only seals the cylinder for combustion so a failure at one point won't compromise the others.

The Boss engine came standard with a single Holley 4-barrel carburetor rated at CFM mounted on an aluminum intake manifold that flowed well for its time.

The Mustang's engine compartment was not wide enough to accommodate the massive Boss engine. Production of the Boss began in at Kar Kraft's new assembly plant in Brighton, Michigan ; the cars were transported to this plant directly from the Ford Rouge plant. The new, revised, front apron assemblies that accepted the large Boss engine had been installed by the Rouge plant as the base vehicles were being built; this produced a stronger and cleaner front structure.

The reworked front fenders were also installed at the Rouge plant. This was the first Mustang ever fitted with a rear sway bar, and so it handled much better than the other large engine Mustangs of the time, making it a much more capable track car. It came fitted with an 8,rpm tachometer, and AM only radio. In addition, a hole was cut in the hood, and a manually controlled hood scoop was added to these cars.

Other features included a front spoiler that was shallower than the Boss spoiler, color keyed dual racing mirrors, and an engine oil cooler. It was also equipped with a 3.

The rest of the car featured a very clean look that was atypical of most Mustangs that Ford had produced, which could be deceiving to some people.

Each car was given a "KK" number which stood for Kar Kraft. Unfortunately sales started to drop off for the Boss Mustangs and with higher production costs, gas costs, and other internal Ford problems, it was decided that would be the last year of the Boss In present day, these cars are highly sought after. The fully functional hood scoop was the same color as the car, and noticeably larger than anything else offered on any Ford product at the time, with the exception of the two Boss Cougars.

This scoop would carry over to the model year but would be painted black on all cars. To this day, it is the largest factory hood scoop ever installed on a factory produced Mustang.

All these cars were a manual transmission, and there was no air conditioning available due to the size of the engine. Though not originally offered as an option, it is common to add a spoiler and window louvers commonly seen on — Mach 1's and Boss 's. Some early cars were known as "S" code cars and as such had a slightly different engine.

These cars had magnesium valve covers, NASCAR style forged internals, nearly no smog or emissions equipment and are said to be more powerful than the later "T" and "A" code engines which had the emissions related equipment to satisfy government regulations.
