The Boss 429 Mustang is a high-performance Ford Mustang variant that was offered by Ford in 1969 and 1970. It featured a race-designed 429 cu in (7.0 L) semi-hemispherical head version of the big block 429 V8, offered in the car both to homologate the engine for NASCAR racing and to offer a bigger, more-powerful version of the popular small block 5 L Boss 302 Mustang.
The price of all the performance and modifications was steep: at nearly $5,000 a Boss 429 was roughly twice the price of the base model inline-6 Mustang. A total of 1,359 Boss 429s were produced.
