Living with 3.91's

Well guys, i originally started this thread and it seems to be a good one. I finally fitted the 3.91's yesterday. Its too early to make any real assertions at this point with just 20 miles under my belt. But those 20 miles included town, country and a spot of highway.
The converor really likes the change. The car is straight off and running compared to the 3.23s. The whole motor seems to like the where the power band is.
Regarding cruising at highway speeds, i can't tell as i now need to change the speedomoter drive as its reading way out. First impressions are positive, though.
