Story

The 1968 AMC AMX 390 is the first-year two-seat AMX at its sharpest: short wheelbase, no rear seat, and AMC's new 390 V-8 as the top factory engine. This page treats the 390 and Go Package as equipment that must be proven by records and hardware, not by stripes or badges alone. It also keeps the 1968 car separate from the later 1970 ram-air redesign and from 1971-up Javelin AMX models.

The strongest public presentation for this page is the equipment boundary: a real 1968 AMX 390 can be a four-speed or an automatic, and a restored Go Package look still needs evidence for the 390, Twin-Grip, brakes, suspension, tires, and stripe path.
