How can it be one of none?
Mr. Norm made 50 Dart GTS's with 440's that he called GSS in 1968.
Chrysler said that a 440 would not fit in a Dart, Mr. Norm ordered 383 Dart GTS's and converted them to 440's. It basically embarrassed Chrysler into doing it for 69. I ran into a guy locally here that had one of the original 440 Dart GSS. His nephew also had an original 69 440 Cuda.
