Specifications
The 1971 Boss 351
Mustang was the last of the true muscle cars of the era. It replaced
both the Boss 302 and Boss 429 from the previous two years as the
performance mustang in 1971. The Boss 351 Cleveland engine stocked 330
horsepower and featured a four-bolt man block, large port cylinder heads
and valves, a solid lifter camshaft, an 11.7:1 compression ratio and
aluminum valve covers. Also standard on the Boss 351 was Ram Air, 3.91:1
rear axle with Traction-Lok, Competition suspension, four-speed manual
transmission, power front disc brakes, front spoiler, lower body side
paint treatment and Boss 351 decals in place of the Mach 1 decals.
A chrome front bumper, instead of the rubber bumper found on the Mach 1,
could also be found on the Boss 351. The black or argent paint, in the
shape of a rectangle, covered most of the hood which differed from the
Mach 1 hood scheme.
Standard wheel were 15 x 7 with trim rings/hubcaps. Optional were the
chrome Magnum 500s, also measuring 15 x 7. Either way, tires were Goodyear
F60x15 RWL.
The Boss 351 had much better low-end response than the previous Boss 302
and Boss 429 models, and its equal weight distribution made for better
handling as well as better braking.
