When American Motors Corporation unveiled the AMX in February 1968, it sent shockwaves through Detroit. Here was a scrappy underdog — a company better known for economy cars — dropping a genuine two-seat muscle car into the heart of the horsepower wars.

The crown jewel of the AMX lineup was its optional 390ci V8, borrowed from AMC’s full-size car inventory and retuned for performance. Conservatively rated at 315 horsepower, the 390 produced a stout 425 lb-ft of torque, giving the lightweight AMX blistering straight-line capability. Paired with a Hurst-shifted 4-speed manual or a 3-speed automatic, the combination was formidable.
