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.

    This is not true. An M22 gearbox has a 20 degree helix angle on the gearset as opposed to a 30 degree angle. It's roughly a 10 degree difference.
