engine spinning at 2500 for a few hours okay?

with the 4.30s gearing, my truck spins about 2500rpm at around 75mph,

could this harm the motor?

Try 4.88's. 2200 at 55. I usually hold right at 2500 on the freeway. Much more and the mileage gets really bad.

Curious, what is redline?

And I think i'm about 2300 at 80 - fuel economy sucks then.

I get the same 2500rpm when running 75mph, with my 6.0L and the 4.30 TowBoss setup. I'm running a stock tires, which I'm assuming you're doing as well. I haven't noticed any performance issues running that speed. Fuel mileage drops to around 12mpg.
