1970 Ford Mustang Boss 429 For Sale - Beautiful Rotisserie
Restoration, Fully Documented LMC is very proud to offer for sale
this 1970 Ford Mustang Boss 429 The Boss 429, sometimes referred to
as the "Boss 9" by blue oval enthusiasts, is arguably one of the
rarest and most valued muscle cars from the era. In total there
were 859 original '69 Boss 429s then only 499 Boss 429's for the
1970 model year. The origin of the Boss 429 was as a result of
Ford's desire to compete NASCAR. Ford was seeking to develop a Hemi
engine that could take on the Mopar Hemi boys - the 426 Hemi
Charger Daytona and the Plymouth Superbirds - the monsters for Ford
to slay to achieve their desire to rule the track. NASCAR required
that at least 500 cars be fitted with the competition motor and
sold to the general public. The Boss 429 engine featured aluminum
cylinder heads, which had a modified Hemi type combustion chamber
which Ford called "crescent". The Boss 429 engine used a single
Holley four-barrel carburetor rated at 735 CFM mounted on an
aluminum intake manifold. All these cars had the Hurst Competition
Shifter 4-Speed Manual Transmissions and the Boss was rated very
conservatively at 375 HP while actual output was believed to be
well over 500 horsepower. Mustangs' were simply too small to accept
the massive Boss 429 engine so Ford hired Kar Kraft of Brighton,
Michigan to modify existing 428 Cobra Jet and Super Cobra Jet Mach
1 Mustangs. Modifications included widening the shock towers and
extending out the inner fenders. The mounts for the front
suspension were chopped and displaced to create room for the block
and exhaust manifolds. The battery was repositioned to the trunk
and a stiff 3/4" sway bar was added to rear end to improve handling
since the car was now nose heavy. It was also equipped with a 3.91
ratio rear axle with a "Traction-Lock" limited slip differential.
In addition, a hole was cut in the hood, and a manually controlled
hood scoop was added. Other features included a front spoiler and
color keyed dual racing mirrors. In short, all Boss Mustangs are
simply big block power with few options. These very special cars
were given NASCAR identification with a "KK" number that was placed
on the driver's side door. 1970, the second model year had very
minor changes and production was drastically cut back. Changes
included the mechanical lifter camshaft and an improved dual
exhaust system though rated power output stayed the same. The
biggest change were the five new exterior colors - Grabber Blue,
Grabber Orange, Grabber Green, Pastel Blue and Calypso Coral. This
Boss was built on September 9th, 1969 at Dearborn and then
delivered new to Larson Ford Sales Inc in Murray, Utah. Open the
hood with the fully functional air-gulping Hood Scoop, which were
all painted Matte Black in '70 regardless of the color of the car,
to find the monster Boss 429 engine. The engine bay is very
detailed throughout, correctly and is complete with all the
production chalk marks, tags and decals. The numbers matching Boss
429 engine is connected to its numbers matching RUG 4-Speed Close
Ratio Manual Transmission with the mandatory Hurst Competition
Shifter. It also came factory equipped with a "V" Code 3.91 ratio
rear axle with a Traction-Lock limited slip differential. This
Boss, representing the rarest production year of the Boss, has
received a beautiful rotisserie restoration. It looks striking in
the rare factory Code "J" Grabber Blue which has excellent depth
and beauty. The interior features the White Clarion Knit/Corinthian
