The Boss 429 is arguably one of the rarest and most valued muscle cars to date. In total there were 1,358 Boss 429′s made. The origin of the Boss 429 comes about as a result of NASCAR. Ford was seeking to develop a Hemi enginethat could compete with the famed 426 Hemi from Chrysler. NASCAR’s rules required that at least 500 cars be fitted with this motor and sold to the general public. After much consideration, it was decided by Ford that the Mustang would be the car that would house this new engine.
In 1970 there were 499 Boss 429′s made by Ford Motor Company. There were five new exterior colors (Grabber Orange, Grabber Green, Grabber Blue, Calypso Coral, and Pastel Blue) and the interior was available in White or Black. The hood scoops for this year were all painted black regardless of the color of the car. These cars also had a manual transmission and no AC was available.
These cars were rated conservatively at 375 horsepower and 450 ft lbs of torque. Actual output was just over 500 horsepower . The manufacturers and dealers only listed 375hp because of legal issues and rising insurance costs.
In present day, these cars are highly sought after. As of 2008, auctions on Ebay and at Barrett-Jacksonhave brought bids of over $250,000.
Peak performance is proud to present their tribute to the Boss 429. A complete rotissore build surrounds this amazing engine. We started with a 1970 fastback which was completely sandblasted and all rust removed and new sheet metal replaced. All new parts were used to improve the handling of this car. New suspension, Wilwood brakes and TKO 600 transmission complete the transformation. Read more!
