1970 Ford Mustang Boss 429 – The Mysterious Muscle
In 1970 Ford had produced some of the best Mustangs of all time: Mach 1, GT, Boss 302 and the Shelby, but the most remarkable and mysterious was the Boss 429. The story starts with the NASCAR racing series, where Ford had entered with their Boss 429 engine as a competitor of the Chrysler’s Hemi 426. Back in the 1970, Ford had to produce 500 (originally there were 859 Boss 429 units produced) street version vehicles with that particular engine to enter in the NASCAR racing series.
But the Mustang never appears on the race track, instead there were Torino or Mercury. The Mustang was the only option to get Boss 429 engine in a street legal car. This mysterious 1970 Ford Mustang is powered by Boss 429 cubic-inch or 7.0 liter V8 engine with Aluminum cylinder heads, factory rated at 375 horsepower at factory limited 6,200rpm and 459 lb.-ft. of torque (actual power is over 500 horsepower and is able to rev up to 9,000rpm). HURST four-speed manual transmission send the power at the 391 rear axle. This Boss 429 is one of the best Mustang’s ever produced.
