The M22 got a drain plug before any other Muncies. Once the 454s reached the option list with 500+ lbs/ft of torque, the need for a transmission that was equal to the challenge was called for, hence the M22 was specified for the LS5 & LS6 cars through 1972. Noise standards for 1973 lead to the demise of the M22, plus the 454 was getting its ...

The M22 was eventually dubbed the "Rock Crusher". It is a common misconception that all Muncie transmissions are "Rock Crushers", but it is only the M22 that deserves that name. The M20 and M21 were both release in 1963, but it wasn't until 1965 that the M22 hit the market. The M22 was created for the Corvette Grand Sport racing program.

An M22 gearbox has a 20 degree helix angle on the gearset as opposed to a 30 degree angle. It's roughly a 10 degree difference. From time to time I get people disputing what exact angles are on the gears. Personally, I think the angles vary from gear to gear. 1st gear on an M22 may be 19 degrees, 3rd may be 20 degrees.
