Tell Me More
The Ford Mustang Boss 429 was born out of necessity. Ford wanted to race in NASCAR, and to do so, they needed to produce a street-legal version of their 429 engine.
Thus, the Boss 429 Mustang was created. It was a beast of a car, though factory ratings understated its true power.
The cars were assembled by Kar Kraft due to the engine's size.
There was no direct successor.
A little-known fact: Ford initially planned to call it the "Boss 429 SCJ" (Super Cobra Jet), but the name was changed late in development.
