This 1967 Plymouth GTX hardtop has the Hemi with dual Carter AFB carbs (above) and four-speed manual, one of only 313 GTXs so equipped. Another 406 had the Hemi and TorqueFlite.
Born at the height of Plymouth's performance career, the GTX also benefited from an upbeat period in Plymouth styling, when clean, taut lines replaced the tailfins and sci-fi grilles of recent memory.
The GTX's corporate B-body (shared with Dodge) was then but a year old, having debuted at Plymouth for 1966's Belvedere/Satellite line. And incidentally, the official name in 1967 was Belvedere GTX, though hardly anyone, including Plymouth advertising, ever bothered with anything but the initials.
The Super Commando 440 was the usual engine in street GTXs; interestingly, it was too big to qualify for NASCAR or USAC competition, which was where the Hemis mostly played.
Of course, you could also find the 440 in two-ton Chryslers and Imperials after 1965 -- but in the GTX it was tuned for some 25 more horsepower: a rated 375 at 4,600 rpm, plus a thumping 480 pounds/feet of torque peaking at 3,200. With 1,400 fewer pounds to push, the 440 made the GTX go like hell.
However, to make sure you didn't wind up there, Plymouth also included beefed-up front torsion bars, rear leaf springs, and front anti-roll bar, plus Goodyear Red Streak performance tires and heavy-duty dual-circuit brakes. Serving "secondary safety" were seat belts all-around, a padded dash top, and energy-absorbing steering column.
In those days all it took to impress a customer was cubic inches. The GTX wasn't sophisticated in today's automotive sense with rear-wheel steering or four-wheel-drive or turbo-charging or multi-valves.
From the outside it didn't even look that special. Aside from a blacked-out grille, dummy hood scoops, quick-release gas cap, and simulated mag wheel covers, it was pretty much like your everyday Satellite two-door hardtop or convertible.
Still, there were bucket front seats (vinyl, of course -- one reviewer compared their appearance to a Tijuana handbag), and you could order a center "sports" console, an electric tachometer there (poor positioning, that), woodgrain steering wheel, five-spoke road wheels, hood/deck stripes and, maybe best of all, front-disc power brakes and Sure-Grip limited-slip differential.
Most 1967s seem to have had these goodies. On the next page, we delve deeper into the 1967 Plymouth GTX.
