3 Muncie 4 speeds were offered. The M-20 wide ratio, the M-21 close ratio, and the "Extra heavy duty close ratio" M-22, also known as the "Rock Crusher". The M-22 was generally installed behind severely powerful (high torque) big-block engines. The M-22 is distinguished from an M-21 by the angle of the gear teeth. The M-22 has "straight cut" gears.

The Muncie 4-speed is a constant-mesh transmission. This means that all the gears in the transmission, except for reverse, are always meshed together and spinning, even in neutral. When you shift you are locking a particular-speed gear to the main-shaft. In reality, only three reduction gears correspond to physical first, second, and third gears.

The dead 2.20 first gear ratio which is the same in the M21 is not that good for off the line acceleration. You would need at least a 4.56 rear end gear to compensate for the dead first gear.
