I know it's easy to put a Muncie or Saginaw 4 speed behind a 230 or 250, but does anyone know if they ever came from the factory that way? I'm mostly interested in the 1966 to 1972 time frame, Camaros, Chevelles, and Novas. I'm looking for something good enough to convince the NHRA to allow me to run a 4 speed behind a 230(first choice) or 250.
