no real updates but thought I would add a little tech - I learned something new when putting my motor together so I figured I would share
I started out with an 07 6.0 LQ4 truck motor - of course I wanted to get as much out of it as possible so I went to Lane Culver for advise. He has learned from past experience that the truck injectors are not sufficient for supplying a motor once you change the exhaust and add a cam. I decided to go ahead and upgrade the injectors so I wouldnt be fighting that battle on the dyno. I found a LS2 intake complete with injectors and throttle body for less than a set of aftermarket injectors so i went for it. with the LS2 intake you are also gaining a 90mm throttle body over the trucks 78mm. Once I had the truck harness cut down and the new injector plugs installed we hooked up the throttle body to test everything. It was a no go. I started doing some research and found out that you must use an X-link system from http://www.torquerush.com/ to make everything function properly.
I also found out that the truck waterpump must be modified to exit from the front like the car pumps do. This is due to the LS2 DBW throttle body controler protruding out to the left where the truck intake controler is on top. This was a problem for me considering the 07 truck pumps didnt even come with the boss on the front that could be cut out for a fitting to be welded in. So I also had to purchase a water pump for an older style truck motor.
The end product was worth the effort as I gained a larger injector, bigger throttle body, more clearance above the motor, and the appearance of the car intake.
