1969 FORD MUSTANG BOSS 429 FASTBACK

During the late 60s, Ford designed a big-block engine for the sole purpose of competing in the NASCAR that was dominated by Chrysler’s 426 Hemi V8. To have a compatible car for the 429 cid “semi-hemi” engine, Ford produced the limited edition 1969-70 Mustang Boss 429. During its two-year production run, only 1,350 were created which made it one of the most wanted collectible high performance muscle car during its time.

Kar Kraft was the one Ford assigned to stuff the large 429 cid “semi-hemi” engine into the limited space of the Mustang Boss 429’s hood. Several changes were needed to do this. The inner front fenders were widened, the shock towers were relocated which changed the front suspension and transferred the 85-amp battery to the back of the car.

For better handling, Ford installed a three-quarter inch sway bar to the suspension in the rear of the Boss 429 which was not front heavy, it was the very first factory built Mustang that had this rear suspension configuration.

All of the Mustang Boss 429 came with 4-speed manual transmission, 3.91:1 rear axle with Traction-Lok, functional hood scoop and front spoiler, dual exhaust, engine oil cooler, competition suspension, power front disc brakes, and power steering.

Ford declared that the 429 “semi-hemi” engine was rated with 375 horsepower and a torque of 450 pound-feet, although actual rating have been known to be well over 500 horsepower.
