1970 Plymouth GTX 440 Six Pack
Although overall the Plymouth GTX averaged more than 10,000 units per year during the four-year production, the 440 six pack was unique. The GTX was available with the standard 440 four-barrel carburetor, as well as the 440+6 barrel (three two-barrel carburetors) and the 426 Hemi.
The more desirable 4-speed manual made this car a joy to drive, pushing over 375HP by some conservative testers, with the Hemi kicking out 425 horses. Unfortunately the 71 model was slammed with restrictions from eco-legislation.
