Author Dan Burrill collaborated with Boss 429 expert Denny Aldridge to give you the straight story of developing this monumental engine, engineering the components and parts to fit the engine and chassis, and assembling the cars.

The Boss 429 has its roots in NASCAR racing. Chrysler's 426 Hemi was dominating NASCAR competition, and Ford's attempt to race the 427 SOHC "Cammer" had failed. By 1967, Ford had enough, and the Boss 429 was the answer. So, Ford and its engineers, with the help of Holman-Moody, returned to the drawing board to create a clean-slate big-block engine to beat the dominant Hemi.

The Mustang fastback chassis was the obvious choice for the engine, but the Boss 429 had an enormous footprint, so it wouldn't easily fit in the engine bay. Although it would have been far easier to install the engine in the full-size Galaxie, these cars were not as popular or widely revered as the Mustang. Ford and specialty car builder Kar-Kraft faced the daunting task of modifying the Mustang fastback to create what's considered to be Ford's greatest big-block muscle car, the Boss 429. This is the story of the car, its equipment, and manufacturing history.

Each volume in the Muscle Cars In Detail series provides an introduction and historical overview, an explanation of the design and concepts involved in creating the car, a look at marketing and promotion, an in-depth study of all hardware and available options, and an examination of where the car is on the market today. Also included are paint and option codes, VIN and build tag decoders, as well as production numbers.
