The original Mustang was re-skinned and became heavier for 1967, but this was boom times in the muscle car market and there was a demand for Mustangs with higher performance. Over the next seven years, which included a major redesign in 1971, Ford fielded a vast array of high-performance options. These options remain quite rare, which makes the Shelby Mustangs, the Mach 1 351 and the Boss models much for desirable today. This book puts everything neatly into context. Contemporary road and comparison tests, specification and technical data, new model introductions, and driver's impressions are all here. Models covered include: Shelby GT350, Shelby 500, 390 GT, 427, 428 Cobra-Jet, Boss 429, 428 Mach 1, GrandT, Boss 302, 351 Mach 1, Trans-Am Mustang, 351HO.
