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.

Most transmissions are missing these tags, but if you want to do a complete restoration they are generally necessary. Even if your Muncie is assembled from a mix of parts, you should be able to determine the ratio. Remember, if the transmission is still in the car only the 1969 to 1974 cases had ratio identifiers in the serial number.

The M-22 was only produced in a close-ratio version, so it will not appear on models with high rear-axle ratios (3.55 or lower numerically) unless someone has changed it.
