1971 Ford Mustang Boss 351 4-Speed

Description

The 1971 Ford Mustang Boss 351 was produced for a single model year and represented the final high-compression, solid-lifter Boss Mustang developed prior to tightening emissions regulations. Built as a performance-focused variant, the Boss 351 featured unique engine components, Competition Suspension, and model-specific exterior and interior trim.

This example is finished in White over a Black interior and is powered by a 351ci V8 paired with a Toploader four-speed manual transmission. Power is sent to the rear wheels through a Ford 9-inch rear axle equipped with 3.91 gears and a Traction-Lok differential. Equipment includes factory Competition Suspension, manual steering, and power-assisted front disc brakes with rear drums. Exterior features include a blacked-out NACA-duct hood, black side stripes, rear deck spoiler, and 15-inch chromed Magnum 500 wheels. Interior features include Black Clarion Knit and Corinthian Vinyl bucket seats and factory instrumentation. Modifications are reportedly limited, comprised of an MSD ignition coil along with long-tube headers and an aftermarket exhaust system.

According to the included Elite Marti Auto Works Report, this Boss 351 is one of 1,806 produced for the model year and is further documented as one of a limited number finished in White with a Black bucket seat interior and chromed Magnum 500 wheels.

This 1971 Ford Mustang Boss 351 is now offered on dealer consignment with a framed Elite Marti Auto Works Report and a clean North Carolina title.
