Ford Mustang Boss 429 Grabber Green

Famed and fabled, the Boss Mustang is the pinnacle of Ford’s pony car production. Seldom seen yet well known, Boss Mustangs were some of the most unique Mustangs ever built. Semon “Bunkie” Knudsen spearheaded the Boss project to homologate the new “Semi Hemi” 429 CI engine for NASCAR regulations, and produce a car eligible to compete in the Trans Am series. Ultimately the 375 HP Boss 429 and 290 HP Boss 302 were introduced in early 1969, and served Ford well in many respects.

In spite of the largeness of the 1969 Mustangs, their engine bays weren’t big enough to house the monstrous 429. Ford contracted with Kar Kraft of Brighton, Michigan to reconfigure the cars to accommodate the 429, and by relocating shock towers, increasing the front wheel track, and moving the battery to the trunk among other alterations, the Boss 429 was ready to go. Only 857 Boss 429s and 1,628 Boss 302s were sold in 1969.

Larry Shinoda was largely responsible for styling the Boss, and in 1970, when the Mustang was lightly restyled, Boss followed suit. Under the hood little had changed; just 499 Boss 429s and 7,013 Boss 302s were sold in 1970

Kar Kraft number 2446, this 1970 Boss 429 is one of 52 produced in Grabber Green, and sports a Black decor group interior complete with the convenience group, Philco AM radio, Rim Blow steering wheel, console, deluxe seat belts, tachometer and electric clock. Featuring mostly original sheet metal and interior, this Boss 429 underwent a comprehensive restoration completed in 2010. The Boss 429 V-8 engine is topped by the famed Semi-Hemi aluminum heads, and like all 429-equipped Boss Mustangs, this one has the requisite competition suspension, power brakes and power steering. A close ratio 4-speed manual transmission with T-handle Hurst shifter feeds the Drag Pack 3.91:1 Traction-Lok rear end and Goodyear Polyglas GT tires wrap chrome Magnum 500 wheels.

Sold new at Minar Ford in New Brighton, Minnesota, formerly owned by Mustang aficionado Jackie Jones and part of a private Mustang collection for more than 10 years, KK no. 2446 presents a unique opportunity to acquire a Boss 429 in Grabber Green; the second-rarest color produced in 1970, the only year for Grabber-themed paint.
