The early 1970s marked a turning point for the American muscle car era. Government regulations and rising insurance costs forced automakers to downsize and de-tune their high-performance engines. Ford was no exception, discontinuing iconic models like the Boss 429 and 428 Cobra Jet in 1971.
However, the company did offer a few final hurrahs with the revised 429 Cobra Jet and the new Boss 351. The revised 429 Cobra Jet was a formidable engine, producing 370 horsepower, a significant increase over the previous year’s 428 cubic inch version. The Super Cobra Jet, with its 375 horsepower output, was on par with the legendary Boss 429.
The Boss 351, while not as powerful as its big block counterparts, was still a formidable performer. Powered by a souped up 351 cubic inch Cleveland V8, it delivered 330 horsepower, a substantial increase over the standard 351 Cleveland. The Boss 351 also featured a distinctive appearance, with its blacked out hood, front and rear spoilers, and prominent side stripes.
Despite these impressive offerings, demand for high performance Mustangs dropped dramatically in 1971. Only a small number of customers were willing to pay the premium for the Boss 351 or Cobra Jet, as the era of the muscle car was drawing to a close.
The Boss 351 Mustang, once undervalued, has become a sought-after collectible. While many examples now sell for over $100,000, this Light Pewter car offers a more affordable option. The exterior has been repainted, but the interior appears original. The Marti Report reveals the car’s rarity, with only 60 examples produced in this color.
This particular Mustang was built as a company car and features several desirable options, including a Traction-Lok differential, power steering, Deluxe steering wheel, Sport Deck rear seat, AM/FM stereo, center console, and Magnum 500 wheels. Despite the repainted exterior, the car remains a solid driver that can be enjoyed without breaking the bank on a full restoration.
