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.
