This fully restored 1970 Ford Mustang Boss 429 is powered by its original 429ci V8 engine and 4-speed manual transmission. It sits on U.S. Mags wheels wrapped in Goodyear Polyglas tires and comes with its Deluxe Marti Report. The highlight of the Mustang Boss 429 was the semi-hemispherical 429ci V8 engine that was put in this car for homologation purposes. To compete in NASCAR, Ford had to build at least 500 production cars with this engine, and the Ford Mustang Boss was born. The engine is topped with an aluminum intake and Holley 4-barrel carburetor. All 1970 Ford Mustang Boss 429s were completed by Kar Kraft and given separate serial numbers; this one is KK NASCAR #2245. This is one of 62 Boss 429s painted in Grabber Blue with a black interior in 1970, according to the Marti Report.
