M22
Standard Close Ratio
These
are the ratios General Motors offered as a factory option. Best
when used with deep axle ratios such as 4.11 and 4.56. Designed
in the days of 40 cent gasoline, it's good for dragsters and limited
street use.
M22W
Custom Wide Ratio (Available Spring '02)
We designed this gearset to run with more economical axle ratios
such as 3.55 and 3.70. For cars that can handle it this is our
recommended street ratio.
M22X
Custom Competition Ratio
We designed this gearset primarily for vintage racing on road
courses where upper gear flexibility is more important than acceleration
from zero. It can be used with very large street motors if the
1-2 ratio drop is not a problem.
M22Y
Custom Overdrive Ratio (Available Summer '02)
We designed this gearset in response to the many requests we have
received for an "in case" overdrive. The overdrive 4th
is noisy and less efficient when compared to the direct drive
4th in a conventional gearset but it can be used in cars where
an axle ratio change is not practical or gear noise is not an
issue.
