Blt2ski and your mech are right. Stuffing 4.88s in a 10 bolt (if they even make that low of gears for them) and running in OD towing heavy with a 4l60 are both not so great ideas.

Don't be too fixated on rpms. LS engines spin up fine. You could run in 2nd gear all day down the highway if you wanted to, barring the screaming engine.
