The Plymouth GTX represents muscle car royalty, introduced in 1967 as the gentleman's hot rod with standard 440 cubic-inch power. This particular specification—440 V8, four-speed manual, and Dana 60 rear axle—represents the GTX in its most desirable configuration. The 440 Super Commando V8 produced 375 horsepower in standard tune, while the rare 440+6 (triple two-barrel carburetors) pushed output to 390 horsepower. The four-speed manual transmission and bulletproof Dana 60 differential were essential for handling the massive torque. GTX production peaked in 1968-1970, with the '68 model featuring the cleanest styling and the '70 offering the most aggressive appearance. The $89,983 current valuation reflects the GTX's status among serious muscle car collectors, particularly for numbers-matching examples with desirable options. Clean, documented GTXs with the 440/4-speed combination represent blue-chip muscle car investments, as their combination of performance, rarity, and Plymouth's racing heritage continues driving values upward.
