Engine rebuild progress w/ pics
I've managed to get a lot done over the past few weeks and should (hopefully) be breaking her in on Wednesday. Just figured I'd post a few pics of the progress.
2005 CTS-V
-Block: LS6 5.7 cleaned, decked, honed (.007 to 3.905)
-Pistons: Forged Mahle -4cc
-Rods: Forged Scat H-beam 6.125
-Crank: Stock, polished
-Heads: Stock 243, new springs, bowl ported, milled .0012 to 62cc (bringing compression back to around stock 10.5:1)
-Cam: GT2-3
-Headers: Pacesetter wrapped in DEI Titanium
-FI: Maggie MP 112 w/ 1:1 rears, 2.8 front, 8"o/d crank pulley(hopefully will be upgrading soon to the 122)
-AEM Meth kit (should keep my IATs under control through the winter and will be adding the super chiller in the spring)
-Misc: King bearings, Comp Cams trunion upgrade, Lunati pushrods, LS2 timing chain, LS7 lifters, ARP bolts throughout, Fel-Pro gaskets throughout
Machine work done by Terry @ Centex Motorsports Temple, TX
Build done by yours truly @ Xtreme Performance Temple, TX
I'll update after break-in, and again after the dyno tune.

Nice build and cool pics man!
I'm looking to get a rebuild here within a few months also.. how much for a motor that's got a spun rod bearing if I want everything replaced internally? I got a quote for around mid $3k w/ a 3yr & 50k mile warranty from another company and want to compare prices..
btw, I will be be doing a complete write-up on my FB fan page for the shop I go with..

Must be an optical illusion...no belt rubbing.

So I broke her in last week the hard way (easy way) with a few 2nd-4th gear pulls from 1/2 - 3/4 throttle. I haven't had it re-tuned yet but Wow she seems to have woken up. It's been a while since I've been able to drive it so it's kinda hard to compare. I've already run into my first problem though after only a week...limp mode from codes P0120, P0220, and P1516. Pretty sure the throttle body is toast, so already time for another upgrade...90mm LS2 tb. Does anyone know if the 06-07 LS2 maggie snout is what I will need? I called Magnuson and they want almost $400 shipped for just the snout. I called Hendrix and they might have one for $200 if they can find it. So I guess I'll be doing this mod before the dyno-tune.

Looks great, put a 102mm tbody on there. You may need an ls3 maf as well.
Were you able to hone it yourself or did it need to go to a machine shop?
Let's see the dyno numbers!

The block work was done at a machine shop. They have to use a torque plate in place of the heads when boring it to get precise and accurate results.
I can't wait to get her on the dyno! I'll keep ya'll updated.

There is no power to be had with a larger throttle body on a Maggie...many have been down this road a while back and were really disappointed. You might see 3-5 whp from tuning, not nearly enough to justify the expense.

Wow...I missed the part where Magnuson is raping people for $400 for the snout. Holy crap...that was $125 two years ago. So, $400 for the adapter, $400+ for the LS2 Throttle body for 5 whp. It has not been mentioned that you cannot use the LS3/7 throttle body as the blade actuates in reverse of the LS2/6 throttle bodies causing instant reduced power mode.
Nobody has ever made 20 HP with the LS2 upgrade on a Maggie. Every one that I have seen never had anything modified in the MAF tables meaning they did not flow any more air than the LS6 throttle body...which means the dynos were fudged to see a 20 whp gain.
