The 1969 Chevrolet Camaro ZL1 has been called the "Holy Grail" of Camaros, as it featured an all-aluminum 427 V8, race-prepped TH400 transmission and 12 bolt rear axle, and they only produced 69 of them. The 2011 Muscle Car & Corvette Nationals held in Rosemont, IL, featured not one.. but 17 of these ultra-rare Camaros. Here, we speak with Jeff Murphy about his ZL1 and the unique restoration showing the car in ready-to-race form.
