1969 Ford Mustang Boss 429
In the late 1960s as the American horsepower wars were heating up, Ford developed an all new engine that became the most fearsome car on the drag strip. Known as the Mustang Boss 429, these cars were only built in 1969 and 1970 as homologation vehicles for Ford’s NASCAR program, allowing them to use their newest big block V8. This 1969 Ford Mustang Boss 492 is one of just 859 examples built in 1969, and is the only example sold through Bickford Ford in Snohomish, WA that year. Finished in Black Jade, this car was purchased by the consignor as a barn find in Stanwood, WA, and sent to Boss expert Mark Bedney at Kevin’s Kassic Cars, to turn it into a show piece.
From the exterior, these Boss 429s didn’t look all that different from a more standard Mustang Fastback of the era. The main indications of what sit under the hood are a large Ram Air hood scoop, lower front spoiler and a subtle fender graphic that states simply “Boss 429.” This example is one of 162 finished in Black Jade, and is fitted with the attractive 15-Inch Magnum 500 wheels, which are wrapped in period-correct Goodyear Polyglas tires. This car was restored to #1 show quality, and won a gold award at the 2020 National Mustang Club Concours in Tucson, AZ and there is no reason it won’t continue winning awards at muscle car shows around the country.
The interior of this Boss 429 was optioned from the factory with the Deluxe Interior Decor Group which fits the car with “Comfortweave” high-back vinyl wrapped bucket seats, a floor console and wood applique on the dash and center console. A 3-spoke wood-rim steering wheel- with center blow horn- frames a set of deeply hooded gauges, and an analog clock sits in front of the passenger. Of the American performance cars of this era, the Mustang’s interior is one of the more appealing and that is especially true when paired with the upgraded interior package. As with the rest of this car, the interior was restored to as it would have been when new, and remains show quality.
What truly separates this Mustang from all the other 1969 fastbacks, is that legendary 429 ci V8 that sits under the hood. This engine was based on Ford’s 385-family of big blocks, and features hemispherical pistons, forged internals and for 1969, hydraulic lifters. An auxiliary oil cooler was installed, and the Ram-Air hood scoop was manually controllable and allowed for the driver to open it and let in more dense, cold air. This engine is immediately identifiable by its large cylinder heads, which necessitated Ford contracting its skunkworks department Kar Kraft, to figure out how to make everything fit. This involved modifications like putting the battery in the trunk and modified front fenders. Ford claimed that these engines produced 375 horsepower and 410 lb-ft of torque, which period dyno tests showed to be accurate. This engine then sent power through a heavy-duty close ratio 4-speed manual, to the rear wheels through a 3.91 Traction-Lok rear axle. Due to the extra weight up font, the suspension was modified with Staggered shocks, front and rear sway bars, and heavy duty springs and shocks. Unlike many powerful cars from this era, Ford and Kar Kraft were sure to address all of the systems in the vehicle to ensure it could do more than just go fast in a straight line.
The Boss 429 remains one of the most sought after Mustangs ever produced and this is without a doubt, one of the best examples available. When you pair that with the long-term Pacific Northwest history, this is a truly one of a kind vehicle that would be an outstanding addition to any serious collection.
