Episode 09: 1971 Mustang Boss 351
The 1971 Ford Mustang Boss 351 arrived at the end of one of the greatest periods in American automotive history. Produced for just a single model year, the Boss 351 combined aggressive Mustang styling with Ford’s high-performance 351 Cleveland V8, creating a rare muscle car that has earned a special place among collectors and Mustang enthusiasts.
Jim Guthrie takes a closer look at what makes the Boss 351 such an extraordinary machine. Factory rated at 330 horsepower, its high-compression 351 Cleveland, four-speed manual transmission, performance suspension, and unmistakable Boss styling made it one of the most serious street-performance Mustangs of its generation. With only 1,806 produced, the Boss 351 is considerably rarer than many of the muscle cars that have become household names.
We’ll explore the history, engineering, and details behind this remarkable Mustang while showcasing the craftsmanship required to restore and preserve a classic of this caliber. For Guthrie’s Garage, working on a Boss 351 isn’t simply about bringing an old car back to life—it’s about protecting a piece of Ford performance history for the next generation.
Join us as we celebrate the 1971 Mustang Boss 351, the final Boss Mustang of the original muscle-car era and a fitting conclusion to an unforgettable chapter in American performance.
