Winner And MCA Gold 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 19th, 1969 at Dearborn and then
delivered new to Owen Ford Sales Inc in Vineland, NJ. 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 shows very nicely,
correctly and is fully detailed with all the production chalk
marks, tags and decals. The numbers matching Boss 429 engine is
connected to its 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 concours rotisserie
restoration. It looks striking in the rare factory Code J Grabber
Blue which has excellent depth and beauty. These cars had just a
very plain external identification with only the White Boss 429
decals on the front fenders behind the bright chrome Magnum 500
wheels mounted on Goodyear Polyglas tires. The interior features
the white Clarion Knit/Corinthian Vinyl Hi-Back Bucket Seats, which
look to the the original ones. Even the restoration of the
undercarriage reflects a high level of the quality restoration and
the detail taken to have this Boss present as you see it here.
