well... assuming a tire change to LRR 185/70-14's, 65mph is 2500 rpm in OD on the 3.73's. In 3.08's it will be 2750 rpm in 3rd! OD will come in at a lazy 2100 rpm.

hmm... flat road cruising at 2100 rpm with a LRR tire/wheel combo that will shed 12lbs a corner. sounds like a winner (providing 2100rpm is indeed more economical to run than 2400 rpm now).
