The Boss 429 was offered for the 1969 and 1970 model years in order to homologate the 429 engine for use in NASCAR. Production was completed by Kar Kraft of Brighton, Michigan, and each example was given a serialized number. This example was assigned serial number 2232. The car was finished from the factory in Grabber Green and is said to have been repainted in 2010. Exterior features include a hood scoop, Boss 429 graphics, a front spoiler, and dual exhaust outlets.
The 15″ Magnum 500-style wheels are mounted with 245/60 BFGoodrich Radial T/A tires. The car was ordered with the a competition suspension, which added staggered rear shocks, heavy-duty shocks and springs, and front and rear stabilizer bars. Power-assisted brakes with discs up front and drums out back were standard on the 429, with the front brakes reinforced with heavy-duty hubs and rotors as well as oversized spindles. Power-assisted steering was also equipped from the factory.
The cabin features front bucket seats and a rear bench upholstered in black vinyl, and woodgrain veneer accents the dash, floor-mounted center console, and door panels. The car was optioned with the Decor Group and Convenience Group packages, and additional interior appointments include a Hurst shifter, a push-button AM radio, an electric clock, and a heater.
The rim-blow steering wheel frames a 120-mph speedometer, an 8k-rpm tachometer, and gauges for fuel level and temperature. Controls for the choke and hood scoop are located on a bracket mounted above the accelerator pedal on the lower dash area. The five-digit odometer shows 34k miles, a few of which were added under current ownership.
Kar Kraft was commissioned by Ford to modify Cobra Jet Mustangs with a larger 429ci V8 featuring “crescent”-shaped combustion chambers. It came from the factory with an aluminum intake manifold and a four-barrel Holley 735-cfm carburetor. Output was rated at 375 horsepower when new. The engine was rebuilt by Mustang Fever in Santa Clara, California, in 2010, and work performed at that time included the installation of a Comp Cams Magnum camshaft kit, camshaft bearings, valve springs, keepers, and lifters as well as custom-fabricated rocker shafts and JE pistons, rings, and pins. An MSD electronic ignition system has also been fitted, and the removed carburetor and spark plug wires are included in the sale.
Power is routed to the rear wheels via a four-speed manual transmission and a Traction-Lok rear axle with 3.91:1 gearing. The transmission was resealed in April 2009.
