Ford Mustang Boss 351
In 1971, the Mustang received another thorough restyle, the final one for the first generation. The car again grew in size and weight. Also, it featured a new sharper look with a much wider track. Unfortunately, the Boss 302 and Boss 429 versions were gone but the Grande and Mach I stayed, albeit with lower power ratings.
However, there was one interesting model Ford introduced in 1971, and that was the Boss 351. They made it for one year only, so the ’71 Mustang Boss 351 was one of the rarest Mustangs ever. In fact, Ford only built 1,800 of them.
It was powered by a highly tuned version of the 351 V8 engine with around 330 HP. It was fast, good looking and more expensive than the Mach 1 version of the same model year. And today, it is a true collector’s item.
