Anybody that knows anything about musclecars knows that muncies were weak. That's why most of the real serious gm racers either used the 833 or toploader. The m22 was real strong but it had a high first gear ratio. I seen more then one muncie explode on the line. Instead of insulting these people maybe the real problem is you don't know what you are talking about?
Why do you think they made a m22 because the m20 and m21 was weak.
The best 4 speed gm had was the Super T10.
