Details

By the late 1960's, Ford was losing ground in NASCAR, due to tough competition from Chrysler's legendary 426 HEMI engine. Their response was to create a HEMI-based engine over their own, the 429. In order for the engine to be approved for use in racing, it had to meet the homologation requirements and be fitted into at least 500 street cars. Eventually the decision was made that the Mustang would be the platform to house the new engine, creating the Mustang Boss 429. With the new engine being so large, the Mustang's engine bay needed to be modified to fit everything. Rather than modify the cars in-house, Ford partnered up with Kar Kraft of Dearborn, MI, to widen the engine bays and install the motors. In addition, Kar Kraft relocated the battery to the trunk and added a 3/4' rear sway bar to help with the weight distribution in attempt to help offset the heavier weight in the nose. The cars were dramatically underrated from the factory at 375hp, but in reality put out well over 500hp. For 1969, Ford produced 857 Mustangs and two Mercury Cougars equipped with the Boss 429 package. Buyers were offered a choice of five different colors, but black was the only interior option available. The cars were rather mild in their street appearance, with the only distinguishing features being the large, fully functional hood scoop and a small 'BOSS 429' decal on the front fenders. This 1969 Boss 429, also known as KK #1717, is one of 271 cars made in Wimbledon White and came well-equipped from the factory with options such as the Traction-Lok differential, 4-speed close-ratio transmission, power front disc brakes, deluxe interior, functional front spoiler and completion suspension. It features its original matching-numbers engine and transmission documented with a Marti Report. The engine received a full rebuild, completed in August 2016, by a Boss 429 specialist in Scottsdale, AZ, with the entire process being photo-documented. The entire car has been restored with great attention to detail, with all components and markings being correct for the car. There were 1,356 Mustang Boss 429s built in total. **TITLE IN TRANSIT**
