I don't know about the Chevelles and Camaros, but I know that in the Nova series, if the car had a six cylinder engine in it, you could NOT get a 4-speed manual trans from the factory. All Novas with sixes were limited to 3-speed manual transmissions or Powerglide automatics. Chevelles were probably the same. If a 4-speed was available behind a six, I'm guessing that it would have been in the Camaros, but I don't really know. Anybody else out there able to shed some light on this?
