Ford enlisted the help of Kar Kraft to wedge the massive ci into the 1969 ford mustang boss 429 Boss Mustang. The Boss engine featured aluminum cylinder heads, which had a modified Hemi type combustion chamber which Ford called "crescent". The Boss engine used a single Holley four-barrel carburetor rated at CFM mounted on an aluminum intake manifold. All these cars had 4-Speed Manual Transmissions and the Boss was rated very conservatively at HP while actual output was believed to be well over horsepower.

It was built as a limited production Mustang Fastback to meet the required homologation of units. Power was legally rated to horsepower kW although horsepower kW was possible. To meet emissions regulations, a mild cam was fitted along with a smog pump and small carburetor. With a few modifications up to bhp was common. Since the new engine was too large to fit in standard Mustang body, KarKraft was hired to modify the front-end of the car into a standard Sportsroof SCJ body.

The Boss Mustang is a high-performance Ford Mustang variant that was offered by Ford in and The Boss is recognized as being among some of the rarest and highly valued muscle cars to date. NASCAR's homologation rules required that at least cars be fitted with this motor and sold to the general public. 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 aluminium intake manifold that flowed well for its time. The Mustang's engine compartment was not wide enough to accommodate the massive Boss engine, so Ford contracted with Kar Kraft of Dearborn, Michigan, to modify 4-speed Cobra Jet Mustangs to accept it. Production of the Boss began in at the Ford Rouge plant, where front apron assemblies revised to accept the large Boss engine were installed during vehicle construction. These also provided a stronger and cleaner front structure, important considerations on such a performance car, and were coupled with reworked front fenders. The cars were then shipped to Kar Kraft's new assembly plant in Brighton, Michigan for engine installation and further modifications.

With more than a half-century of production, the Ford Mustang is an institution of American highways. Lauded for its sharp styling, lightweight construction, and excellent handling, it has been a best-selling American sports car throughout its run. While American car companies have scaled back their offering of cars in favor of crossovers and SUVs, the Mustang stands strong and appears to be a part of the American auto industry over the next half-century. The last two decades of Mustang have spawned many special editions with modifications from the factory as well as aftermarket tuners, such as Saleen and Roush. But there was a heyday for special edition Mustangs before in the late '60s, providing us with great cars such as the Shelby GT, Cobra Jet, and Mach 1. Great as those cars may be, the Boss is the baddest and most powerful among them all. With a giant V8 in the relatively small Mustang chassis, the Boss is a tire-shredding tour de force. Although it may not be as well known as others, it is a cool car to have a closer look at.
