If you have an LS3, stock internals along with headers,exhaust,and dyno tune should hold 650rwhp ALL DAY LONG. just do ARP bolts to make sure nothing comes loose! Running meth injection also helps ALOT!

I think i'm gonna do some more research, i've been told getting up to 570rwhp on the L99 with out forged internals is about the max it can handle by 2 tune shops and a manager in the parts department for edlebrock... another 80rwhp is quite a significant increase, unless the L99 isn't built to handle as much as the LS3? this i dont know... going through the forums, it just turns into a pissing match rather than factual information about how the two motors differ other than vvt and afm.
I'm also not sure what meth injection is, still kinda new to all of this.
But what i do know is the L99 SC from edlebrock comes with a 3.875" pulley, where as the LS3 kit comes with a 3.5" - so if you're willing to part with it, i'd definately like to know.
