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?

That is what my truck does as well. Nothing to worry about except crappy fuel mileage!!

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.
