I'm starting to take that 120day warning personally haha.
Update for this year - I pulled the plug on the turbo motor. I still have a Dart CCW crank, Dart CNC heads, and a bunch of other stuff but no block.
When I started down that path, I was getting great help from the marketing director at the parent company to Dart, supply chains were full, and timelines were limited by me. As time went on, the prices ballooned and even if I were willing to pay retail, delivery times went from "6 months" to "who knows" for some of this stuff. Depressing, and I've had other cars to spend money on:

The Hummer will forever stay with us - still haven't swapped the Duramax in.
New Cayenne Turbo for the wifey, downpipes and a tune.
911 Turbo S is what I drive most days - stock turbskies but upgraded everything else on pump gas + methanol.
Trackhawk is getting sold eventually.
RX7 is getting moving again finally, and not pictured is one last GSXR1000, all sharing a 4-car garage.
In the end, I went sentimental and 'simple' over "huge power" and 'massively expensive' - I nabbed a COPO LS7 customized by GM Racing for Conrad Grunewald's Formula Drift Camaro a bunch of years back, which was the team I was closest to (personally and professionally) 2009 to 2014. Those early seasons flying around sleeping on couches and doing my thing, growing my business will always be nostalgic for me, so having a piece of that really feels good.

My girls have no idea how loud this thing is haha.
It's a max-effort N/A monster that I didn't particularly like driving in the Camaro, but I think that's because of the 7.25" button clutch and non-existent flywheel that car used.
427ci Wixom-stamped block, billlet main caps, 13.5:1 forged Mahle pistons, I believe Callies forged rods, CNC LS7 Wixom-stamped heads, GMPP LS7 stage 3 cam, CTSVR lifters with 1.8 trunion rockers, Katech dry sump pump. Word is they took a COPO LS7 and did every little grey-beard trick to make more power because this wasn't limited by NHRA rules.
As I recall, they originally made something like 740hp on race gas, and I'm hoping for ~650whp on E85.
I got a set of Ronin headers since I sold my JTR's and a Tony Mamo-ported MSD Atomic intake will replace the Hi-Ram since I'm fond of running a hood lol.
At the advice of GM Racing, I'm going to run the Katech dry sump and Camaro Z28 oil-to-water cooling block which both use the LS7 pan, so I'll be modifying my Hinson subframe to lower the steering rack and clear the oil-to-water setup. I bought the pinto bump steer kit that Cryptic and some of the rest of you awesome guys talked about to replace my Samberg bump steer correction stuff.
I got a deal on a Peterson 6in x 19.5in dry sump tank that will fit just in front of the passenger tire, above the diffuser. I've got some nice 1.75" tube structure up there so hopefully I can package it and the lines above the lowest parts of the car. Stoked on the short lines running to LS7 dry sump pan on the passenger side.

The pile of parts grows...

On the electronics front, I already have an AEM Infinity and CD7 dash w/vehicle dynamics module I'm very fond of, so added the 8x EGT kit and a ECU Master PMU16 (thanks for the keypad deal Blake!).

I've got brake pressure sensors and a string pot I'm going to attach to the steering shaft under the dash for steering angle, so just need to figure out how serious I am about shock pots and I'll have a good set of data.
I'm downsizing from my 2k hp fuel setup to a single twin-screw Fuelab 500lph in the fuel cell, and trying just the 15x15 Hydramat in the cell for slosh control. Now that my fuel needs are ~1/3 of what they were, I'm hoping I can ditch the surge tank and the lift pump setup and simplify my life. The new pumps need an external brushless controller (still PWM'd off my Fuelab 529 regulator's feedback signal) and a bulkhead passthrough for the wires into the fuel cell, but still less power, quieter, and more efficient (fuel used to get hot with the old setup in traffic)
SUPER stoked to get this thing together and have fun with it again.
I've really enjoyed seeing the FB updates from some of the crew here and look forward to adding to the collective knowledge as I push this heap a little further down the road.
