The whine of the Rock Crusher is about as much of a muscle car sound as high compression headers and tappet noise I think this is a perfect time for one of those Tim Allen "Argh argh argh " Shoot those s with a close ratio give an even better first gear than the s with the ST 10

But it had a perfect spot on the bottom for resting on a floor jack My Muncie did not sit on the jack very well I made a wooden cradle which worked outside of the car but made the trans sit too high to roll it under the car You could try that Maybe you have more ground clearance A Muncie only weighs about 75 lbs without shifter

Transmission is a Muncie 4 speed I believe it is a wide ratio although it goes through the gears quite quickly 1 2 and 3rd in 5 seconds feels like a close ratio In 1970 I had a new 70 SS 454 LS5 Chevelle with a M22 rock crusher trans and a gear At that time it was my daily driver I lived & worked in primarily all residential
This bumbed me out since I had previously read that this was an indication that it was a Saginaw not a Muncie It does have a 7 bolt side cover Doe this mean it s still an M22 but just manufactured at the Saginaw assembly plant or it s not an M22 "Rock Crusher Transmission" I am just learning
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
