The M22 is a heavy-duty close ratio standard transmission. Some call it the "Rock Crusher".
Does it fly off the line? M20 has a lower 1st gear. Some high performance cams don't "take off" until 2800 or more. A wide ratio tranny would be better in this case.

Here is a table I put together to study rear end ratios and manual transmissions. I've got 323's and an M20. I plan to eventually go with the Autogear unit with the 2.98 first gear
