Here is my thread outlining my mod path with dyno results and track results. Perhaps it will help you.

Not to take away from the OP.
I too am currently deployed but coming back very soon from a 9 month deployment and I am having my GF pick up my 2005 Corvette Z51 LS2 that I just bought this weekend. This is going to be my post-deployment/re-enlistment toy and I was also looking at doing some mods to this bad larry.
With out further ado, Alvin what was the cost of that build, and also I am somewhat local, at Ft. Benning down in GA and I wouldn't mind making a trip up to the shop to get the parts and installs done during a long weekend. I'm looking for reliable(somewhat) raw power, I don't mind looking at supercharger/turbo options either but I'm not trying to blow 10k-15k on top of buying the car when I come back. I am open to any suggestions.
Thanks

Oh, well the FAST intake will probably get me close to 450. With everything stock, the FAST intake may get you +10 but with my mods working in conjunction I *might* get 15-20. Who knows. I never really felt the power gains were worth the cost of the FAST intake. (No offense to anyone that purchased one)

We just did another setup for a customer who wanted a really well rounded hot street setup (this is a LS3 car) anyhow we went smaller with the cam and matched it perfectly to the heads we used. Anyhow this car also had a stock intake manifold. Here's what we did for him

They were Advanced Induction ported heads and a medium sized custom cam. Stock intake mani. No idea what kind of MPG he is getting, sorry, I don't imagine this setup hit the gas mileage too hard though especially since it was a manual car.

LS2s dont hit those numbers with LS3 heads. The highest I've seen was 482 using the same cam with them. Trick Flow 225s are the head of choice on the LS2. Cars run 10.5s with them and the G6X3 cam.

LS3s hit 500rwhp with small cams without touching heads or bumping compression. If fact I've never seen a ported LS3 head do anything substantial to justify even touching them. I do think bumping compression helps your cause so plan on thinner gaskets.

This response is dead nuts accurate. Bank on it.As another data point, I hit 474 in my car with the smaller G5x3 and AFR 205 heads I got for free. 10.8 @ 128 are the best I can do, perhaps a better driver could do better.
I read from Jayplayss2 who just put in the G6x3 and runs stock ported heads that it drives very well, it certainly puts out more torque than my setup, like 40 more lb ft. Here is his dyno from a 234/242 size cam to the G6x3. Gains across the board.

With AI ported 267cc LS3 heads this LS3 C6 put out 517/485 with a G6X3. The photo states it's an LG proprietary CNC program. That's pretty dang stout. http://www.advancedinduction.com/LSX...cGM823Head.php

On LS2s with Trick Flow 225s and the G6X3, guys put down 530rwhp so it stands to reason that the Trick Flow 225s on the LS3 would be making 15rwhp more just by displacement. Save your money and get a proven head instead of porting stock heads that make near nothing in gains.

I hit 485/433 ls2 with ls3 ported heads. I have run almost 132 mph and ran 6.41 in eighth and 10.15 in quarter. Hp numbers dont tell it all. I have seen A LOT of 515-570 hp cars struggle to run 132. Just get the combo right and you will be happy!
