The Pick of the Day is one of the iconic 1969 prototypes built by Kar Kraft for Ford, turned into a quarter-mile competitor
One of the most-iconic of all muscle cars, the Mustang Boss 429 was created by Ford to take on the big guns in high-speed NASCAR racing, but quite a few of them found their way onto the drag strip.
Arguably the most-famous of the quarter-mile racers was Boss 429 No. KK1213, the fourth prototype built by Kar Kraft for Ford, and since the earlier prototypes are no longer with us, it is the earliest Boss 429 known to exist. It originally was raced by Dave Lyall, a test technician for Ford who competed with the car in the NHRA, with the assistance of Ford’s Total Performance racing program.
The Boss was restored during the ownership of noted Ford collector Richard Ellis, who 10 years ago found KK1213 for sale on eBay and, during the restoration, reunited the car with its original numbers-matching 429cid engine. It retains the parts with which it originally raced, including the dual Holley 750-cfm carburetors on a high-rise Weiand intake manifold that Lyall developed for NHRA Pro Stock competition.
“A recent restoration finished in its racing livery recreated exactly as it was raced most of its life, all the details have been painstakingly reproduced even down to the hand- painted sponsorship graphics,” the seller says in the ad. “November 2017, KK1213 was shown and judged at the Muscle car & Corvette Nationals, where it was awarded concours Gold and scored 986 out of a thousand (judging documents available).”
The Boss 429 has a robust competition and ownership history. In the ClassicCars.com ad, the current seller provides a link to a magazine story in Mustang 360, an enthusiast publication that zeroes in on its full history, including technical details of its build by Lyall.
The seller does not provide an asking price in the ad, requesting potential buyers to make contact. According to the Hagerty Price Guide, a 1969 Mustang Boss 429 ranges to value from $229,000 for one in good condition to $430,000 for concours condition.
But KK1213 is a very special Boss, and its provenance as the earliest example and with noteworthy racing history, as well as restoration to its period racing spec, should make it worth quite a bit more.
