Cost to go 9.99?
People have gotten 800hp out of the stock lines, presuming you have the fuel pumps to keep your fuel pressure. Turbo would likely be a PT7675 or a TC78 running E85 with a good tune. Probably running around 21 psi.
Chinese head or ARP head studs. (big cost differential)
Hotside (truck manifolds most cost effective)
If you run E85 you won't need an intercooler
Twin 255lph or 340lph fuel pumps in-tank or a single 244/340 intank with another pump inline.
80# Injectors
Good Head gaskets
Transmission will also make a difference on the reasonable ET expectations.

That tune Is going to be ultra important
A stock 5.3 will run 9.99 in a light enough car. You can do head gaskets and studs to keep the heads pinned on better.
Stock bottom end 03 LQ4, TU1 cam, 4L80e with an HD2, circle-d converter, Turbonetics 7875 1.15 ar on 14 lbs., 3.25 gear, E85. The car weighed around 3450 with me in it. It was a 1SC car with no power options.

Outstanding!! These motors amaze me. I used to look at my friends Supra with envy back in the late 90's because he could just use the stock block, crank, rods and pistons and get over 600 while my LT1 cried if I went over 500 on those same stock components. Now comes the awesome 4.8's and 5.3's and they make Supra stuff look weak.
Thanks for sharing. I knew your ride was quick but I didn't know the LS9 cam was involved. I bought a brand new LS9 cam for $135, but was kinda talked out of it. I'm sure my ISKY Triple 12 will do great as well but I sort of wish I'd tried the LS9 cam first.

Following year I tried 10:1 alum 5.3 (243 heads) with trip 12 cam. It was the exact opposite. A tire fryer before boost even hit. Handful to get dialed in on the track as well, even with 28X12 slicks. This setup was finicky to tune fuel/timing/traction wise. But still a blast. Id lean towards low compression stuff for the novice LS builder. Gives you a large forgiving tuning window.
