Default LS9 cam+LS6 intake pull FI 4.8 to 8k?

Will an LS6 intake would be better than the NNBS truck intake from 7500 shift points and 8000rpm trap speeds?

Or if anyone knows or has links to a LS9 carrying power to 8k?

This is a roll race deal being built for the Texas Mile,

2012 Sierra 1500 RCSB 2wd
Under 3,700LBS on race day
4.8 SBE, filled to water pump
85mm+200 shot+E85+Meth?
TH400 + Gear Vendors O.D.
6,500rpm stall+4.56 gearing

NNBS is the better bet

I would run something like a Holley low ram for that RPM. Why a LS9 cam? That cam leaves a lot on the table for that setup.
