For gas, you will notice a diff going from your 2.73's or 3.27's? (whichever) to 3.73's. I noticed about a 2 to 3 mpg drop, about 30/40 miles less per tank (15 gal tank x 2.5 mpg).
for speed,
I cut this post from MYTKWIK on another site...
qoute "
3.73s at 6000rpm with 26in tire = ~124 mph
4.10s at 6000rpm with 26in tire = ~113 mph

Here is the formula if you want to do you own calcs.
(rpm * tire diameter)/(axle ratio * trans ratio * 336)

AODE Gear Ratios:
1st: 2.40
2nd: 1.47
3rd: 1.00
4th (OD): 0.67
Reverse: 2.00
