I believe all first gen Z/28s were available with only the close ratio Muncies. This would be the M21, which most had, and the M22 which very few had. You're right about the guy being way off. Guys always say they've got a rock crusher when they are refering to any Muncie, there are big differences as we know. The M20 is a great trans though.

People think the "Rock Crusher" is special or stronger than a standard wide box Muncie. It is special in terms of price but it isn't any stronger. The "Rock Crusher" was built for road racing, with the angle of the gears straightened out to prevent excessive wear in the front bearings due to the forward thrust component of the force vectors ...

The M22 Rock Crusher would come later to accommodate the heavy twist of Chevrolet's big-blocks in the mid-1960s. The M20 and M21 transmissions produced from 1963-'74 are easy to identify in both wide- and close-ratio units.

True enough the M22 did trickle out the door in 1965-67 and was buried in the option lists. It was around 1968 that easy to find the M22 on option lists, but the significant extra cost was a way to dissuade all but the most serious of gearheads. Drain plugs came to the M22 first, as did the fine splines.

Again, the only tried and true way to tell if it's an M22 is to pull the side cover and look at the gear angle. Vince
