The Stovebolt Site Forums The Shop Area Engine Shop More SM420 questions

Since I'm a relative newbie to this area, I'll ask some newbie questions.

Is the SM-420 the designation for the "granny 4-speed?"

Is that the usual suspect for what I'd have in my 64 C10 with 292 I6?

And is there supposed to be a dash in there or is it SM420...or does anybody really care.

Thanks,
