The Boss 429 is one of the rarest editions of muscle cars that can be found around and that’s what makes it one of the worthiest cars.
It is a car that has a very distinctive and unique development story.
Unlike the drag package cars that we are used to, the Mustang Boss 429 is a mix of Mustang, NASCAR and an impassive expression that hides what’s within the car. This 1969 Ford version even though it got bigger it was still a great success and a closed deal that was selling big time.
The engine is a NASCAR part – a fired – up no truck Ford 385 block that has semi semi-hemispherical heads. That was the ballistic missile of Ford that was pointed directly at the Mopar Camp and the 426 Hemi. Ford had to mass produce 500 identical engines and offer them to sell to the public in order to qualify for homologation. The real question is how did the exceptionally large engine got squeezed into the Mustang. To make the huge mill jam into the Mustang – Kar Kraft that was in collaboration with Ford worked on the front end of the mill, hacked it and cut it and the thing was done.
The Ford Mustang Boss 429 had to compete against the Barracuda and the Challenger with a 426 Hemi under the hood that were 425 HP rated, as well as against the COPO ZL – 1 Camaro with its 427ci Rat with a conventional 430 HP. Still Ford took on where its predecessor the Boss Nine have sat – 375 HP and 450 ft/lbs of torque. If you accept that fact as true, we have to tell you that you are pretty foolish. The 1969 Ford Mustang Boss 429 had been pushing way past that number at approximately 500 HP for base measures. The restored version with small carburetor, headers and the additional modifications performed must be surpassing those figures. Jay Leno gets to tool around with a freshly restored Mustang and that makes his first drive in a Boss. We know it is very hard to stop yourself from envying him.
