Wicked 1969 Mustang Boss 429 Still Looks Showroom Fresh

1969 Ford Mustang Boss 429

Big block pony has the original 390-horsepower V8 with only 18,000 original miles on it.

It’s good to be the boss, right? To be the one at the top, the one calling all the shots. In 1969, the big block Boss 429 was at the top of the Mustang portfolio. With an engine designed to do battle on NASCAR ovals across the country, it was a high-performance racer that you could order right from your local Ford dealership. Nearly 50 years later, Boss 429s are still at the top of the heap for collectors. But this 1969 Boss with 18,000 miles on the clock might just be the Boss of Bosses.

Offered by Mecum at its Kansas City auction, Dec. 6 – 8, this Boss 429 looks like it never left the showroom. Finished in Wimbledon White over a black vinyl interior, this Boss has just about every option you’d want.

That’s a lot of Mustang


The massive original 390-horsepower V8 is paired with a four-speed close-ratio manual transmission. That sends power to a rear axle fitted with a Traction-Lok differential and 3.91 gears. Magnum 500 wheels wear Goodyear Polyglas tires, just like they did in 1969. Power steering, power brakes with front discs, and a competition suspension package help keep this beast on the road.

Inside, things are beautifully preserved. This Boss has a center console, bucket seats, and the Interior Decor package. For the glovebox, the car comes with its build sheet, shipping invoice, and a letter from Ford with build specifications. There’s no word on whether it’s original or restored, but either way, this is one of the most beautiful Bosses we’ve ever seen.

With a Boss like this, it’s likely that it will live out the rest of its life as a garage queen. We’re fine with that – it’s an incredible example of Ford’s best circa 1969 and it should be preserved. Still, we hope that whoever buys this car will take it out and drive it in anger at least a few times a year. After all, it’s one thing to be the Boss. But you still have to get out there and show everybody how it’s done every now and then.
