with the 3.55:1 first and the 0.68 OD how are you finding the OD gearing...

i have same box and was toying with a swap to 0.72 OD before i fit it but won't bother if the 0.68 is usefull

i run 3.45:1 rear but have a 3.7 and a 3.89 if i need it

It's enjoyable on the highway. 80mph is about 2600rpm and even down low, it pulls OD quite well.
