In 1970, you could buy any kind of Mustang you wanted, from a six-cylinder automatic to the Big Daddy Boss 429 with a four-speed—and everything in-between. Motor Trend’s April 1970 issue picked the top three Mustangs to compare: the Mach 1, the Boss 302, and the mighty Boss-9. As you’d expect, the 429’s prodigious torque (rated at 450lb-ft) made it by far the quickest, with a 5.3-second 0-60 time and a quarter-mile timeslip of 12.3 seconds at 112mph, but it wasn’t a stocker—the car had been set up for B/Stock racing by Chuck Foulger, former head of Ford’s drag-racing activities at the time and owner of a successful Southern California dealership. To read the complete story, check out the gallery for pages from the 1970 article that ran in Motor Trend.
