ALUMINUM will get you well into the 9s
my gto was only at 12psi and went 10.7 with a 1.8 60ft
we turned it up to 22psi for ***** and giggles and damn.
never went back to the track on the 22psi but mph on our local (hwy track) the car was trapping 142ish babying it out of the hole,
stock production block with studs

Stock bottem end '05 5.3 here. Been throwing 6, 9 and now 14lbs boost on it, seems like it is still laughing at me. Zero knock, 12.5-13 deg timing full boost, 10.8-11.0 AFR, 82% duty cycle on 60lb injectors.
Trust me when I say this, boost is very addictive. What a rush

Well the fuel system will be purchased with the f1 thru brute speed. He gives a damn good discount on packages. (Twin walbro with 80lbs injectors are like $215 extra or something like that)
My 6.0 will be n/a probably until the 2014 holley ls fest
