 I do not claim to be a transmission expert and could be wrong but the "real" rock crushers had straight cut gears....not helical cut gears. I believe they were first released by GM in 1969 or 1970. I had one in my 1970 Chevelle SS 454-450HP LS6 car. I bought it new. The Rock Crusher was very noisy due to the straight cut gears.  Maybe someone in the past (it has been 30 years) put all the goodies in a early case maybe? <img src="confused.gif" border="0">

The m22 was available as early as 1965 in Corvetts

I had a 71 GTO with a M22 "rock crusher". This was an absolutely stout transmission. Had a distinctive "whine" due to the slanted gears.

Many people have guesses about deciphering M-22s. Like grooves in the input shaft and numbers and etc etc...
The only way to tell is to open the case and measure the gear angle from the shaft centerline. M-20 and M-21 have 45 degree gears and M-22 have 22.5 degree gears. Fresh M-22s are going for $1300-$1600
