- So Joe, In regards to this message, just what is your observed RPM (more-or-less) with the 3.89 @ 70+ mph? I'm assuming there should be no difference in tranny (early vs. late) because of the 4th gea

- I went through this decision process a while ago and came to the conclusion that the 3.29 would be too low unless you were running a bigger or highly modified engine. This was based on advice from ma
