1968 Plymouth Road Runner

Plymouth went back to the basics when they created the 1968 Road Runner. After deciding that muscle cars had gotten away from their original purpose of being fast affordable thrills, Plymouth paid Warner Brothers $50,000 to affix the ”road runner” cartoon bird onto its new vehicle, which was based on a stripped Belvedere, thus in 1968 the Road Runner was born. The standard engine was none other than MOPAR's tried and true 383 power-plant V8, included the heads, manifolds, camshafts, crankcase windage tray, and valve springs from the race ready 440 Magnum. The new Road Runner was also equipped with heavier duty suspension, manual transmission, and numerous other performance pieces. Comfort was basic with no carpeting - just rubber floor mats and a bench seat. Mopar performance seekers were pleased with the new addition, as the base price started at just $2896 and for just $714 more the Hemi 426 could be had.
