An LS6 Chevelle is hard to find, but it's a great car to do because it's really a collector car—everybody likes a '70 Chevelle and the LS6, that's just a bonus. This one doesn't have cowl induction, but it doesn't make any difference. With that rock crusher trans and the 4.10 gears, it's just a cool car. —Bob Priest ...

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.

Identifying Muncie 4- Speeds. Several things are needed to identify a Muncie correctly. The first is a main case casting number. Second a count of the input shaft and output shaft splines and if any rings or grooves exist around the input shaft splines. Third are date codes and VIN numbers that help confirm that the above case and gears belong together.

8. The M22 Rock Crusher 26-spline input shaft sports a wider gear for greater torque capacity. Just because you've found a 26-spline input shaft does not mean you've found an M22 input shaft, which is made of a stronger alloy. The standard 10-spline input shaft found its way into new Muncie M20 and M21 transmissions from 1971-'74.
