If you ask any Mustang enthusiast in the present day about the Ford Boss 351, they'd probably tell you it's one of the most desirable Ford muscle cars from the era, the last of its kind. That's because Ford only made the Mustang Boss 351 for a single year. The Mustang Boss 351 was only produced in 1971 at the tail end of the muscle car era. The Boss 351 had simply gone out of style just as fast as it raced onto the drag strip. Yet despite its short life, the Boss 351 has made quite the impact thanks to its dramatic dual hood scoops and 14.1-second quarter mile sprint.
