The Mustang Boss 429 was built by Ford for one reason – to qualify the engine for NASCAR racing. These special high-performance Boss 9s were assembled by Kar Kraft facility in Brighton, Michigan. At Kar Kraft the front shock towers were modified and the battery relocated to the trunk to make room for the huge engine that dominated NASCAR. In 1969, production ran from Jan-July and 858 were produced.

This highly documented 1969 Boss 429 is accompanied with a Deluxe Marti Report ,Erminger build sheets, Kar Kraft quality checklists, Letters from Ford, and many other supporting documents are identified as Boss 429 NASCAR KK #1333 and is the 118th produced of only 858 total ever produced and 118 of approx 150 early S-Code Cars (Note: The first 15 KK #1201-1215 were 'test' cars or prototype)only 201 Boss 429s were painted Candy Apple Red of the 858 Bosses total. Furthermore, according to Steve Strange's Boss 429 update, only 135 Boss 429's are known to exist!

Under the hood, KK 1333 was originally equipped with the 820-S Series early NASCAR motor utilizing NASCAR-spec heavy duty rods, forged pistons and steel crank. These early rare S-Series motors were designed to run all day at 9000 rpm and only in the first 150 built.

This excellent early production Boss 9 example presented today originally was born as above with the 820-S Code engine and sold new in Arizona on February 13th, 1969 as however it has been retrofitted with the later production internals of the approx 708 post S-Code builds (note part number in photo)

Ford realized that in order to make these cars more user-friendly for civilian use and to meet emission requirements of the time they had to equip the later production Modle's with minimal smog equipment and a smaller set of rod bolts and a smaller crank ( AKA - T- Code/Series Components)

Ford found that this retrofit reduced warranty issues and continued the equipment (T code components) for remaining production models throughout the two year (1969-70) limited production of only 1358 total Boss 9s ever.
Also, the infamous hood scoop is noted as the badge of the Boss 9 Cars and was the largest of the Mustang line. Additional equipment includes Magnum 500 Wheels, period Correct Goodyear tires, and radio.
