Gear swap question...

I was toying with the idea of ripping out my 3.42s for either 3.73s or 4.10s and one thing I was wondering is what effect this would have on my RPMs in 6th gear.

Right now Im only turning about 1500 rpm at 65ish... so people with 3.73s and a 94+ T56.. what change in RPMs did you see?

I'd enjoy the added jump in acceleration, but I also enjoy getting good gas mileage when I go on trips...
