Muncie also had a second close-ratio transmission designated M22 and often referred to as the "rock-crusher," which was used behind the highest-performance engines and in Corvettes, the M22 is a highly sought-after performance transmission. It is the heavy-duty version of the 2.20:1 ratio M21 four-speed. ... M22 gears are also made of a ...
I went with the " tommy gears" at 2.99 1.88 1.35 1.00, a 3.91 rear and 27 " tall tires. It has the nice rock cruiser whine but its not over top loud. They do have a break in procedure. Don't let it idle in neutral with the clutch engaged . This lets the input shaft spin but nothing else and doesnt let the oil circulate.
In 1965, GM introduced an even more robust version of the Muncie transmission, known as the M22 or "Rock Crusher." This transmission, with its distinctive whine, became synonymous with high-performance cars of the era. The M22 featured straighter cut gears, providing a more aggressive gear mesh for increased strength and durability.

Wide, Close, or Rock Crusher ... The M22 'Rock Crusher' featured a one-inch countershaft pin bore and shot-peened gears with aggressive helix angles that reduced heat and stress but also increased noise, leading to the nickname as the transmissions rattled their way down the road. The upside to the racket was the ability to hold even big block ...
In the early 1960s, GM was looking to move away from the four-speed manual transmissions it had been purchasing from BorgWarner and bring production in-house. The twist was the four-speed gearbox found in the first two generations of the Chevrolet Corvette—the BorgWarner T10—had in fact been built using plans …
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 ...
Although the gears are not spur gears ( completely straight ) they still produced a fair amount of gear noise thus the "Rockcrusher" name. These 4 speeds sound like a blower drive. For the real gear head the best documented movie that sports a real M22 in a car is the famous movie " Two Lane Black Top". You can really hear this gear box howl in ...

It tells how to pick out what is what but the main thing to look for in a M-22 is the gear angle. Take off the side cover and look at the angle of the gears. M-20, m-21 will have 45 degrees gears and the m-22 is 22.5 degrees. They used this to reduce friction and in turn gave it a nice greary noise thus the rock crusher. Chris
""You can outfit an M20 or M21 with Rock Crusher type gears, OR actually make a 3 speed O/D out of a 4 speed case. Forth being the overdrive obviously.. Kinda nice if you want the Muncie look and an overdrive"" Actually the 3rd gear station becomes the OD and the 4th gear station becomes 3rd,so the shift pattern is a little d,1-2-4-3.
