Compliments of cadivette @ http://ls1tech.com

I don't post a lot on here, but spend quite a bit of time reading y'alls posts.
I built a twin turbo set up for my 05 V in 2008 with pretty good results until #7 went south. It floated a valve and havoc ensued!
The car has sat with very little being done to it until last month.
Fast forward........
This is my new build,
Callies Compstar 4" stroke crank
Compstar rods
Wiseco -15cc pistons
Custom ground Comp
PRC stage 2.5 LS6 heads
SRP rockers
Twin Turbonetics 60-1's (rollover from the previous build)
Here's the link to my build progress

I have to say thank you to Texas Speed for the help picking the parts and answering all my questions.
Hopefully I'll have this thing up and running within about another month.
Let me know what you guys think.
Looking for around 650 reliable horses. With the ability to turn it up if need be.
Just finished up the fuel system with twin Walbro 255 pumps.
One more hurtle will be the differential that is notoriously weak on these cars. i've got something cooking for this though.

Got the heads on last night. New ARP studs, LS9 gaskets, and the PRC stage 2.5 LS6 heads. I had a scare torquing down one of the heads when a stud started to pull out of the block. Fortunately I knew when to stop and pulled it back apart. The block had a little excessive casting material in it that didn't allow the stud to thread all of the way in the block. I made a thread chaser out of an old head bolt, cleaned up the threads, and the stud went in. That's a pretty big scare when you get this far along in a build. I was a happy boy whne it all worked out and there was no drama when I went through the final torque sequence @ 80 ft. lbs.
I'll be making a new timing chain dampener today or tomorrow because the LS6 style dampener is not available any longer. I have some fiber material that I'll be cutting the new dampener out of. More fab work, my favorite. If I could just fab stuff up all day and make big $$$ at it, what a wonderful thought!
Anyhow, here is a pic of the finished long block, and an update on my photobucket account.

I still need to check my pushrod length, install the windage tray, oil pan, valley cover, front cover and rear cover then time to put it in the car.
