If the car just sounds different with no accompanying vibrations to co with it chances are your bearings are fine, it might just be a resonant frequency in your exhaust at that rpm.
It's possible it's a resonance frequency because of the long tube headers but who knows. I'll try seeing if there's any play in the crank pulley but you would hear it at idle while revving If there were.
