I have a Muncie in every single GM vehicle that I own. I like the M20 ratios better and most of my cars have 3.73's in them. M21 and M22 ratios are just a little to low (numerically) for anything that I drive on the street. You can buy an aftermarket M20 gearset now with the M22 gear angle if you are looking for the strength of an M22 gearset.

M20s are the most fun to drive in my opinion. Everyone seems to want a M21/M22 without realizing what the actual difference is. The M21/22s just don't have the hole gear to make it with any gear numerically lower than 3.73.
