Paul,
 
A 3.77 will change the engine speed by -10.66351% in every  gear 
((3.77/4.22)-1)x100.
 
The overall gear ratios with a 4.22 are 9.4106, 6.2034,  4.3888, 3.57012, 
2.9751.
 
The overall gear ratios with a 3.77 are 8.4071, 5.5419, 39208,  3.18942, 
2.65785.
 
This assumes stock ZF ratios of 2.23, 1.47,1.04, 0.846,  0.705.
 
For the same red line engine rpm, the 3.77 will go about 11% faster  in each 
gear with about 11% less acceleration. Looking at another way, for a  fixed 
road speed the engine will run 11% lower rpm.
 
Have fun,
