Agree 67 was the prettiest, black one with a Hurst used in Bullett (losing many hubcaps in the process), good 440 can pull a Hemi to any sane speed, big difference is in modern tires.

BTW reason they called a M22 that was not because it could crush rocks but because the straight cut gears sounded like it was crushing rocks. Being partly deaf helped. Only really good thing was that once you burned up the clutch sliding the start, it was no longer needed. Just pull back really hard and bounce the gas pedal when you wanted to shift. Now you know why Hurst shifters had such a stout lever.


ps there were four GM four speeds at the time:
Light duty Saginaw
Wide Ratio Muncie M20
Close Ratio M21
Heavy Duty M22
but for big engines they bought the standard three-speed from Ford.
and later Saginaws were made in the Muncie plant.
