11. Last Boss – Ford Mustang Boss 351
In 1971, Mustang received another thorough restyle which would be the final one for the first generation. The car grew in size and weight again and 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 introduced in 1971. It was the Boss 351.
Made for one year only, the ’71 Mustang Boss 351 was one of the rarest Mustangs Ford produced at only 1,800. 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. Today, it is a true collector’s item.
Also, this was one of the quickest muscle cars of the period and one of the quickest classic Mustangs ever. The powerful 351 V8 managed to launch the Boss 351 to 60 mph in 5.8 seconds, which is fast for an analog muscle car from the early ’70s.
