Rock crushers, like the cone crushers we''ll be discussing in just a moment, generate incredible force to break raw material into smaller pieces. Once material exits the crusher, the user can refine it further to arrive at the final size.

The M22 transmission has a 20 degree helix angle on the gear set as opposed to a 45 degree angle found on the M20 and M21 and were made with a higher nickel alloy. The straighter angle was designed to produce less end loading of the gear train and less heat but created more noise, thus the nickname "Rock Crusher" was born.

In 1958 and later years, Pontiac used the "standard" transmission interface used also by Chevy and other GM makes. So you can bolt up a later Pontiac or Chevy transmission onto an earlier Pontiac bell housing (back to 1958). For example, a ''65 Corvette "Rock Crusher" M22 4-speed will bolt up to a 58 Pontiac bell housing.

The term "rock crusher" refers to the noise made by the meshing of the stronger helical gears in the M22. Later model 1971-''74 Muncies are also popular with racers, because these transmissions used a 32-spline output that is stronger than the early 27-spline, and the newer units seem to perform better in high-rpm and high-horsepower applications.

''64-''65 transmissions had a few differences from ''66 and up (smaller countershaft) All Muncies I''ve seen from ''71 on up had 26 spline input, TH400 size output, and drain plug like the M22s.....leading to the unknowing paying big $$$$$ for an alleged "rock crusher" that really wasn''t.
