Racing homologation models are often the fastest, most pure, and most desirable cars on the collector market. The car offered here, the legendary 1970 Ford Mustang Boss 429, is certainly no exception. In the late 1960s, Chrysler ruled NASCAR with its legendary 426 Hemi engine but Ford decided to go all out to catch up. They developed a 429-cu. in. version of the Ford 385 V-8 with specially modified oil and water passages, four bolt main bearings, and all forged steel internal components. Ford gave the new engine an insurance-friendly rating of 375 hp, though the actual output in stock form is said to be well over 500 hp.

To meet NASCAR’s engine homologation rules, Ford chose to place the new 429 into the Mustang, thereby creating the highly desirable Boss 429 Mustang variant. Originally offered for the 1969 model year, the Boss 429 continued for 1970 and was offered in five factory colors, including eye-catching Grabber Blue, the original color of the car offered here. With just 500 examples completed, the 1970 Boss 429 was and is one of the most desirable factory Fords ever built and is in fact rarer than the 1969 model which saw 839 examples produced.

The car offered here is an overwhelmingly original example of this limited-production muscle car. The car has never been fully restored and has seen just a single repaint in its correct shade of Grabber Blue. It still wears the factory-original code TW White vinyl interior. It has had just four owners since new, including nearly 30 years in proper heated storage in the hands of its third owner. Removed from this long-term storage approximately three years ago, the fourth owner has had some $10,000 in recent work completed, including the fitting of a period-correct carburetor and reproduction export brace. The owner reports that the car runs and drives as expected and is fully ready to be enjoyed.

Included in the sale is an extensive file of historic documentation, including copies of the Ford Motor Company dealer contracts, along with the original sales invoice. Also included is a copy of the Marti Report that fully documents the car’s build history as well as invoices for the engine work. In short, with its incredible originality and documented history, this may be an unrepeatable opportunity to own one of the most desirable examples of one of the toughest Mustangs of the period.
