I've been doing some research on Draglist.com and found some interesting data.
The first Revellution car raced in the 1971 season. It was a completely blue Plymouth Cuda, different from the traditional color scheme of these cars, with white sides and a different color roof.
Between 1972 and 1976 McCulloch only raced Dodge cars, first the Demon and then the Dart, alternating roof colors between blue and red.
But in the 1977 season there were two cars, first a Dodge Dart and, in mid-September, a Plymouth Arrow debuted. It was the only time these two cars had a pink roof.
The list of cars by year:
1971 - '71 Plymouth Cuda
1972 - '72 Dodge Demon
1973 - '71 Dodge Demon
1974 - '73 Dodge Dart
1975 - '75 Dodge Dart
1976 - '76 Dodge Dart
1977/1 - '76 Dodge Dart
1977/2 - '77 Plymouth Arrow
Well, putting all the pieces together, I imagine that the car in question is actually a '76 Dodge Dart that raced at the beginning of the 1977 season. It turns out that, in the Revell kit, a different body is offered, I believe a '73 Dart or Demon. In this kit, the engine is behind the windshield, very different from the car in question.
Well, I think I'll have a lot of work to do from now on to make this kit look like this car.
