Legendary Design Plymouth GTX 440 1968 Reliable – Plymouth GTX 440 became a bit curvier in 1968, and its position as a luxurious hot rod was reinforced by Plymouth’s more affordable and basic introduction to Road Runner. Machine options remained unchanged from the previous year and continued that way until 1969. The tensile test showed that Super Command 440-cid V-8 led 426-cid. With a rear axle of 4.10 440 motors, the Plymouth GTX can turn 0-60 mph in 5.8 seconds and a quarter mile in 13.7 seconds at 102.8 mph.
The interior of the Plymouth GTX 1968 basic bench seats are unreasonable and there is no carpet only mats of rubber. A hardtop coupe and functional hood ventilation were added mid-year during 1968. A horn that beeps complements the standard street runner stickers on all Road Runners. The 1968 Road Runner is probably the second most significant muscle car to the 1964 Pontiac GTO as it shifts the market back to the bang to get the buck roots.
