The Boss 351 was perhaps best known for its significant performance merit. Under the 351’s hood resided a 351 cubic-inch V8 produced 330 HP @ 5,800 TPM, and 380 lb-ft of torque @ 3,400 RPM. The Boss 351 achieved 0-60 MPH times of just 5.7 seconds and was capable of covering ¼ mile in under 15-seconds.
The Boss 351’s tenure was short-lived, as it would be dropped from production after the 1971 model year. Upon its retirement, Ford discontinued the Boss lineup in its entirety, as the company’s focus continually shifted away from race-related endeavours. Today, the Boss 351 is highly sought after, due to its relative scarcity, as only 1,806 such Mustangs were ever produced.
