I would go with the 3.73 gear if you have an 8.2 10 bolt. The 3.73 has a bigger diameter pinion gear and will be a touch stronger.
On the freeway its about a 9% jump in rpm from 3.73 to 4.10's. 2000 rpm vs. 2180 rpm.
Another thing to consider is how well your car runs at low rpm? Sometimes you end up with a lumpy engine with a big cam and it wont run at 2000 rpm down the freeway in OD with a lock up converter. you might need the 4.10's
I've got a 700r4 -410s -275 /30 20 in tires and I turn about 2200 rpms at 75 mph.I'm very satisfied with the way it pulls in the first three gears and then it settles down and cruises at between 70-75 with out killing the motor.
