It's a closely fought contest. The 1970 AMC AMX 390 Go Package brings its unique character to the table, and the 1968 AMC AMX 390 answers with its own distinct appeal. Both are excellent machines that reward their owners in different ways — there's no wrong answer here.
Few model names carry as much weight as the AMC AMX. The 1970 and 1968 iterations represent different chapters in this storied nameplate's history, each reflecting the priorities and technologies of its era. On paper, the two are remarkably close in power output, with the 1970 AMC AMX 390 Go Package producing 325 hp and the 1968 AMC AMX 390 delivering 315 hp. Under the hood, the contrast is notable: the AMC AMX uses a V8 OHV displacing 6,392 cc, while the AMC AMX relies on a V8 with 6,391 cc. Both trade at comparable values on the collector market, making the choice between them largely one of personal preference.
