In the late 1960s, facing stiff competition in NASCAR from Chrysler, Ford developed a new 429-cubic inch V-8 with all-new free-flowing cylinder heads, an aluminum high-rise intake manifold, a 735 CFM Holley carburetor, 11.0:1 compression, header-style exhaust manifolds, and a beefy four-bolt main block, conservatively rated at 375 horsepower.

When dropped into the Mustang, it created the Boss 429, a pony car with abundant muscle. To handle the power, the stout “Toploader” four-speed manual transmission and a 3.91:1 Traction-Lok rear axle were mandatory options. Other features included an engine oil cooler, a trunk-mounted battery, a competition suspension with front and rear anti-roll bars, power front disc brakes, and wider F60x15 tires. The production process required numerous modifications to accommodate the new engine, including cutting and relocating the shock towers. To alleviate the in-house production burden, Ford had the cars sent to Kar Kraft, of Brighton, Michigan.

The Boss 429 was the priciest non-Shelby Mustang to date, at $4,087, and it was available in very limited numbers, with fewer than 900 produced for the 1969 model year.

Rolling off production line in Dearborn in 1969, this is one of only 859 examples produced worldwide, and equipped with the improved 429ci engine, putting out a huge 500bhp. This matching numbers BOSS has enjoyed an extensive professional restoration, as result it is described as being in as new condition.   

Arguably one of the rarest and most desirable muscle cars you can buy, this is an excellent example of the ultimate incarnation of the classic Ford Mustang.
