I bought a 70 Plum Crazy challenger convertible several years ago, at that time I wasn't very familar with those cars then and I called a friend who walked me thru it . It was badged as a R/T but had a 340 in it. The hood and rear exhaust were factory installed so was the 340, what I didn't know about was the A66 code that was the 340 H/P package labeled as the Scat Pack. 340 cars could be ordered with this option giving it the Scooped hood, 14x7 rallye wheels, F-70-17 white letter tires, wheel opening mouding delete, larger radiator, big brakes, H/D suspension and the transverse tail stripe and Scat pack bee decals on the quarter glass giving it the look of an R/T. These cars are are very rare so look for the H vin for a 340 and A66 code on the data plate. My car turned out to be one of a handfull of Plum converts . Just a note that 340 will surpise even the best Big Block , then add a 6 pack and have Fun.
