For the swinging year of 1970 and the debut of the fabled Rapid Transit System, the popular, upscale GTX line underwent subtle styling queues. Like the rest of the B-Body Plymouths, the body style was basically the same as 1969, the nose and the rear end were restyled, and the sides featured a cleaner treatment. The GTX was now available only in a hardtop; the convertible was gone. The twin-rib, fresh-air intake system was changed to the legendary Air Grabber, which was hardly noticeable when closed. Three engine options were available: the 440 four-barrel, 440 6-bbl, and the 426 Hemi.
Plymouth produced 678 GTXs with the 440 + 6 package and 72 with the Hemi for the '70 model year
The car shown here is one of those 678 Holley-tri-carb versions owned by Lynn and Pat Wilson of Muncy, Pennsylvania. Their acquisition of this rare gem came about in June 1976 when the second owner of the 51,000-mile car decided it needed a new home. Once at the Wilsons', the GTX immediately underwent the necessary steps required to be factory fresh.
First on the agenda was completely disassembling the car and making an accurate judgement about its condition. The body was stripped, then sent to the body shop, where the years of Pennsylvania salt treatment were removed from the rear quarters via cutting and new replacements. Once the car was returned home, Lynn, his brother, Steve, and good friend Keith Sampsell proceeded to perform the careful task of restoring the Plymouth to its as-built glory.
For the next three years, fluorescent-lit nights and weekends were spent in the garage as Lynn and the gang spent whatever available time they had on the car (when you deliver packages in a big, brown truck for a living as Lynn does, free time is a rare commodity). When Lynn thought the body was ready to shine, he applied the correct shade of PPG-mixed EV2 Tor-Red acrylic enamel.
Meanwhile, work was beginning on the interior. Though the GTX was considered a musclecar, the list of options offered in the upscale model was quite big. The factory three-speaker dash was refurbished and the Rallye Dash cluster retains all the original gauges, including the functioning Tic-Toc-Tac. For sound at speed, the original owner had the AM/eight-track radio, which still cranks out the tunes through the front three speakers and the two rear factory-installed units. All the windows are factory-tinted and operated by the original power units. Once the car was ready, Lynn covered the worn factory buckets, including the six-way adjustable seat on the driver side, with new skins from Legendary Auto Interiors.
Rather than risk damage to the original motor, Lynn opted to rebuild another 440 HP motor and save the correct engine for future use. The second block was sent to Super Stock power guru Gary Hettler in Montoursville, Pennsylvania, who filled it with .030 overbore 10.0:1 compression pistons spun by a steel crank and Six Pack-type rods. In keeping with the stock idea, a pair of cast 906 heads that were given the requisite freshening and put back in service reside on top of the engine. Just as the doctor ordered, a brace of Holleys round out this tire-frying combo.
Backing up the motor is an A-833 four-speed yanked into the gears by a console-filling Hurst Pistol Grip shifter. Completing it is a set of original 15x7 Rallye wheels wrapped in wide (for the day) F60-15 Goodyear Polyglas tires that are turned by a 3.54 filled Dana rear.
Although the rarity and high-quality restoration of this particular car allows it to hold its own at rest in any show field, you're more likely to see Lynn and Pat Wilson quenching their thirst for excitement on the highways of their hometown in northeastern Pennsylvania. If it were ours, we'd have ordered an Orange Crush to go too. Ahhhhhh.
