What you will get in our 'Syracuse' M22 is a gearset that is stronger, more durable and cooler running. The gearsets are available in three ratios: The classic Rock Crusher M22 (2.20/1.64/1.27/1.00) for your 3.73:1+ rear axle gear. The AutoGear wide M22W (2.56/1.75/1.36/1.00) for your 3.42:1 – 4.11:1 rear axle gear.
This makes the M20 much stronger than the Saginaw or T10. The 4-speed Muncie came in three versions. Both the wide-ratio M20 and close-ratio M21 debuted in 1963 in the Corvette. The M22 "Rock Crusher" followed four years later. It uses stronger components to handle big-block power. The original M20 was only offered for one year.
