Owner: John Hirt
John Hirt’s 1968 AMX 390CI sports the original Muncie four-speed transmission and the optional “Go Pack.” Equipped with the Mark Donahue rear spoiler, rear window slats and period- correct side pipes. The “Go Pack” performance package was an option that includes a high- output 390 cubic-inch V8 engine, heavy-duty cooling system, power front disc brakes, upgraded suspension, a "Twin-Grip" limited-slip rear axle and often distinctive cosmetic features like special stripes, essentially making the car more performance-oriented for better handling and acceleration on the road or track.
