The 1969 Ford Mustang Boss 429 (also known as the “Boss 9”) is arguably one of the rarest and most valued muscle cars of all time. In total there were 1358 original Boss 429s made and only 859 made in 1969, the best year in United States history.
The Boss was born as a result of Ford competing with Chrysler’s famous 426 Hemi in NASCAR’s Sprint Cup Series (at the time it was known as the Grand National Division). NASCAR required Ford to sell 500 cars with the same engine to the general public. This was called NASCAR’s homologation rules. Ford decided to house the engine in the Mustang. The engine was so big that Ford could not fit air conditioning in the car.
The highest valued 1969 Ford Mustang Boss 429 is worth between $300,000-$350,000 with only 97 miles on the odometer.
The 1969 Mustang Boss 429 was available in five different colors, Raven Black, Royal Maroon, Candy Apple Red, Wimbledon White, and my favorite, Black Jade. All interiors came in black. The hood scoop came in the same color as the car, and larger than anything else offered by Ford at the time. To this day, it is the largest factory hood scoop ever installed on a factory produced Mustang.
All the Boss 9’s cars had a manual transmission. In some cases, the engines were removed from the Mustangs for use in other applications such as tractor pulling, due to the extreme horsepower and torque the engine was capable of.
