10 Fastest Mustangs
How Fast Were They Then, and How Do They Stack Up Now?
'69-'70 Boss 429
With all the praise heaped on the Mach 1 and Boss 302, the Boss 429 Mustang must have raised the expectations of the magazine road testers. Even though Super Stock and Hi-Performance Cars posted solid 13-second times for the '69 Boss 429 (apparently with the same car obtained from a Ford dealership), they were less than flattering with their headlines of "Ford's Not-So-Boss 429" and "Boss Loss." It almost sounds as if they were expecting a 12-second factory musclecar right out of the box, and they were disappointed when the big hemi-headed 429 mustered only 13s. However, Car Life came away impressed, even with a 14.09 e.t., as they tagged the Boss 429 as the "best enthusiast car Ford has ever built."
