As one of the rarest and most revered muscle cars of the era, the Ford Mustang Boss 429 represented the peak of Ford's muscle car performance wars that began in the 1960s. Built not simply for the street, the Boss 429 also served as a homologation special allowing Ford to compete in NASCAR and crucially leveled the playing field with Chrysler who dominated the late 1960's with their 426 Hemi. With specially modified oil and water passages, aluminum high-rise intake manifold, four-bolt main bearings, and all forged steel internal components, the specially developed 429 cu-in V8 was conservatively rated at 375 horsepower, likely to appease insurance companies, though in reality actual output is widely claimed at well over 500 horsepower.

Specially built by Kar Kraft, Ford would produce fewer than 500 of the Boss 429 for 1970, combined with the 839 examples built in 1969 to satisfy homologation requirements and allow Ford to compete with their new powerplant. According to its Deluxe Marti Report on file, this example, finished in a striking Grabber Blue exterior, was ordered through Earnhardt Ford of Chandler, Arizona and is one of 285 models finished in the distinctive and iconic blue for the 1970 model year. While the early history of this example is not known, when it was purchased by the consigning estate in December 1992 the vehicle was found in remarkably preserved condition that has remained thoughtfully preserved for over 30 years.

Many similarly high-powered Boss 429s were driven hard and bear the consequences of such use, often losing their originality along the way. It is therefore a true rarity to find an example that not only retains its numbers-matching engine and its correct transmission but also remains largely unrestored with factory paintwork still intact, as confirmed by accompanying paint meter readings. Displaying just 30,809 miles at the time of cataloging, this highly original Boss 429 was recently serviced prior to the auction and represents a remarkable opportunity for a collector to acquire an incredibly well-preserved and unrestored example.
