Muncie rock crusher identification

Aug 23, 2021

Jun 13, 2017 The Muncie four-speed was produced in two ratios: the wide ratio (M20) and the close-ratio (M21). That being said, there was a second, close-ratio version (M22) that was developed to survive duty behind engines with a higher torque output, and was known as the “Rock Crusher.”

    Jun 28, 2010 The whine of the Rock Crusher is about as much of a muscle car sound as high compression, headers, and tappet noise. I think this is a perfect time for one of those Tim Allen Argh, argh, argh. Shoot, those 4.10's with a close ratio give an even better first gear than the 3.31's with the 2.64 ST-10

An M-22 “Rock Crusher” has no rings, so if you see rings in your transmission, it means it is not an M-22 “Rock Crusher.” How do you read a Muncie date code?
