I hate waiting. I'm coming out of my skin. I was going to try to get the intercooler moved while I wait but the peer pressure is insisting that I wait to do it until I get the motor back together and do it all in one step.
Picking up the motor tomorrow. Should be back on the road by this weekend.
The Improved Racing Oil Pan Baffle System bolted right in without any modification to the pickup or the pan.

I don't believe that uneven length pipes make much of a difference so I wouldn't hesitate to build a kit with the turbo in the location that you mention. 2.5" pipe merging into the T4 flange should work nicely. My stock bottom end let go at 15-17 psi and 6500 RPM. That was BONE stock. No rod bolts. No cam. Others have had better/worse luck. Unfortunately, you really don't know when you've reached the threshold until you cross it.
Got the motor back and got some numbers from the engine builder.
Bore is still 4.030 (untouched since last build)
Eagle Crank is same 3.622
Pistons come out of the hole .007
The Childs & Albert Rods are 6.125
Wiseco pistons have 25cc dish
Heads were milled to 58cc
LS9 headgaskets are .051 compressed and 4.100 bore
I'm coming up with just under 9.2:1 static. I thought that it would be higher.

I thought that my compression was around 9.1 before. When I pulled the motor out due to the 2 problems I was having (high coolant temp and low hot idle oil pressure), he ended up having to mill the heads down .015 to get them flat which brought the CC's down to 58cc. I think that the larger head gasket bore diameter of the LS9 gaskets helps cushion some of the SCR vs the smaller diameter opening on the 6.0L head gasket.

May as well post an update.
I got the motor Tuesday night and started working on it Wednesday. When I first built the turbo setup a few years back, I ran into a problem right from the get go with melting the poly motor mounts. At the time, no one made a solid motor mount replacement for the poly mounts. We ended up making a set which turned out to be a bit more difficult than we anticipated due to the offsets and the need for perfect alignment since they have no play. After a great deal of tweaking, we got them on and everything seemed to work right. Problem is that I didn't mark them from side to side and top and bottom. When I dropped off the motor to the builder/machinist, I told him to mark them before he removed them if he did in fact end up having to remove them. Well, I guess that he forgot. So when I got the motor back, the mounts were in a box with the bolts. I took a stab at putting them on the way I thought was correct but once we got the motor up in the car on the kmember with the transmission attached and everything, it was obviously crooked. At that point it was pretty late and I was burnt out and disgusted so I went home and decided to buy a set of professionally made solid mounts that are now readily avialable. Only problem being that I have Steve's (LS2Formula) garage and lift tied up with my car and he really needs it back to but his car back together after the fire from a couple of weeks ago. So I got home at 11:30 PM EST and PM'd Motovativeto see if he could overnight me a set. Within 30 min I had a reply and confirmation and they just got here today. Hope to be on the road tomorrow.
LS2Formula has them on his car running 7's. I have no doubts that they work.
She fired up tonight with little effort and strong oil pressure. Tomorrow we verify timing, bleed brakes, check transmission fluid and fill her up with water. Of course it's supposed to rain all weekend but if all goes to plan, she should be stretching her legs tomorrow night.
