Mustang Boss 429 FeaturesNamed for its powerful 429-cubic-inch Semi Hemi V-8 engine that was a derivative of the Ford 385 engine, the Boss 429 was a race-ready Mustang capable of competing in the NASCAR’s Grand National Division, now known as the Sprint Cup Series. While the Boss 429’s official horsepower rating was listed at 375 hp, many Mustang historians claim it could actually deliver well over 500 and even close to 600 hp.
The Boss 429 also featured a more conservative exterior design than other high-performance Mustangs of the era, although it did include a distinctive, fully functional hood scoop. The scoops for the 1969 models were painted the same color as the vehicle, while the 1970 scoops were available in black only.
A Favorite of Classic Car CollectorsFord produced only 859 Boss 429 vehicles in 1969, followed by 499 units in 1970. A combination of dwindling sales and high production costs caused Ford to discontinue the Boss 429 after the 1970 model year.
Its relative scarcity and robust performance has made the 429 one of the most sought-after Mustangs by classic car collectors. Complex Rides ranked the Boss Mustang 429 at #5 on its list of “The 100 Best Mustangs of All Time.”
