Slider701,

Good point; I am running 3.54 gears and I have .68 OD (Tremec TKO). In fifth gear I do feel like I lug a little everywhere but 65+ and at 70 mph I think rpms are about 2200; I ran on the track at VIR and in the straights, 5 gear really didn't really grab that much at all; went to about 115-120 mph in 4th but to take the next step in 5th seemed like too much work for the engine so waffled around between 4rth and 5th.

So if I couldn't find the top end on the track, and I am looking for a little pop on the street, seems like I could handle moving to 3.70s (or lower)?
