This 1971 Ford Mustang BOSS 351 has received a no expense spared professional ground up restoration. Packing a high-output version of the 351-cu.in. Cleveland V-8 under its broad, tapered hood, the Ford Mustang Boss 351 represents one of the Blue Oval’s last true muscle cars. Just 1,806 were built in 1971, their lone year of production, and they remain among the hottest performers in the world of small-block Fords. The Boss 351’s main claim to fame was its R-code V-8, whose 330hp at 5,400 rpm and 370-lbs.ft. of torque at 4,000 rpm would outgun a number of big-blocks. But the engine was just the beginning of the Boss’s goodness. The 351 was bolted up to a Hurst-shifted four-speed manual transmission, with a Traction-Lok 9-inch rear end equipped with 3.91:1 gears. All came with the beefed-up Competition Suspension package and power front disc brakes. Externally, they were marked by their twin, functional NASA hood ducts, Mach 1 honeycomb grille, lower body paint treatment, body side stripes and 351 decals.
