You should be safe on a n/a engine, considering I've had my redline set at 7500 rpm for over 20k miles and it's been fine.
But with your mods I would be weary of revving it that high. Do some datalogs and see what your a/f ratio looks like at those RPMs.
On a side note, if your revving your car to 7600 rpm with a supercharger and nitrous
, I should be perfectly fine revving my car to 7500 rpm with just minor bolt ons.

Peak power on the v6 is at 6500 RPM. It holds within 10 hp of peak power all the way to 7500 rpm. Revving that high is worth it when racing so that you can take advantage of the hp up top from 6.5-7.5k. Even though it's not building more power, it's still making more power than if you were to upshift at 6500 rpm and land in the 4500 rpm zone.
