Not much new to report, other than I removed the drivetrain assembly and installed the clutch and Tilton 6000 hydraulic throwout bearing. Prior to that I checked the alignment of the bellhousing and was pleased to find that I don't need any adjustments (i.e. offset dowels).
In case it helps anyone else, I used an alignment method prescribed by Silver Sport Transmissions. It's very simple and straightforward. They describe it in this video:
Using this method, I ended up with a final number of 0.0025, which is within the 0.005 tolerance required by Tremec. I believe the smallest available offset dowel 0.007, which wouldn't help here.

Pardon the absurdly large photos... I must have forgotten to resize correctly.
Pretty good weekend, got the final drivetrain install done. I'm sure other LS builders will agree that this setup sits in there very nicely, but no surprise given the dimensions are similar to the SBF. The crank pulley sits about an inch (maybe a hair less) above the cross member, and that's with the FFR LS mounts and no spacers. Very happy about that. As can been seen in the photos, I rotated the fuel rail 180 degrees and converted the quick-connect to AN.
The trimmed Quicktime bellhousing sits about dead even with the bottom of the 4" tubes. Crappy photo, but you get the idea:
I was able to get the transmission aligned within spec to the rear end with three 1/4" spacers from Forte:
And finally, as I think I noted previously, the shifter landed in a perfect location without having to cut any of the chassis.

Again, it's been a while since my last update.
My primary focus now is getting everything in place required to start the engine. I've got the wiring harness and PCM installed, along with the primary power wiring. As you might imagine, there are no lack of fancy billet PCM mounts out there, but I chose to go with an $20 GM unit from eBay that's made of some sort of plastic or poly material. Apparently using a conductive mount can lead to ground looping issues.
The fans are all wired and tested. At low temp, both Spal fans move at half-speed and they barely make any noise. At high temp, both fans run at full speed and I think they could suck a small child into the radiator. Still pretty quiet though. The relay box is installed on the 3/4" tube in the engine bay. The fan harness is specifically for dual fans and the LS platform/PCM.

The fuel lines are all in place and pressure tested with my compressor and soapy water. Good old-school leak test. Of course I'll double check when the system is pressurized with fuel. The regulator sits just inside the passenger side rear wheel well and is very accessible.

One thing I'll need to figure out is the connection to the lower port on the radiator. The tow loop is right there and doesn't provide much room, so I think I'll need to trim or remove it completely (maybe replace with a threaded tow hook like you'd see on many modern vehicles). Other than that, the routing is pretty straightforward.
