So, it would seem the next model to be introduced in the Z8 lineup is the Z06.
There seem to be two paths (so far) in terms of engines (this assumes the expensive twin-turbo will be saved for the ZR1/Zora):
1. A version of the normally aspirated 5.5l flat plane crank V8 from the C8R. This would be tricky from the standpoint of vibration with that displacement. The Ferrari 458 with 4.5l of displacement in a flat plane crank (FPC) application had 570hp and 597hp in the Speciale. So you could lower displacement and get over 600hp. You could also do a hybrid electric motor setup with this, but cost could be a factor with the more advanced and more expensive engine. Someone needs to ask Chevy if the C8R needs waivers as IMSA rules state that the engine has to be based off of a production engine. Ford got waivers for the GT so they could race it before customers got cars. If Chevy got waivers then we'd have a better idea if there is pressure to get the FPC DOHC V8 in the Z06. If there were mules with this engine, we'd probably hear about it.
2. The LT2 engine with an electric motor. The only other C8 mules we've seen since the introduction have had the LT2 engine with some electric plugs hanging out of holes near the frunk. A bystander said one of these mules pulled away silently. So if the LT2 is 495hp and let's say a version of the Bolt EV 200hp electric motor were used, then you'd be knocking on the door of 600hp no problem with quite a bit of torque on the bottom end. GM can probably go higher on the EV motor horsepower output with more minimal battery storage since the Corvette application isn't a straight EV but a hybrid setup. Weight balance would be better with the electric motor up front (but overall curb weight goes up even more) and effectively it would be an AWD type setup that should catapult the car crazy quick.
Bodywise, the C7 Z06 had wider front and rear fenders. The C8 is already pretty wide (but 2 inches less than a Ferrari 488 as comparison), but they could do it. Will it have a version of open fenders at the rear like the C8R? Obviously wide-open like the C8R would be a mess kicking up stones and debris all over the sides of the car and people driving behind you, so they would likely box them in and use screening inside the fender liners if they did. The C8 already has fairly wild styling and if Chevy ends up adding a ZR1 and a Zora at the very high end, then they will need to leave something on the table for those versions. They could also make the carbon accessory pieces part of a standard kit with a carbon version of the Z51 spoiler or something slightly more aggressive. Should be interesting to see.
Guessing debut would be at the Detroit Auto Show next June 2020 with a market launch later in the year if it follows the C7 timeline.
I'm happy to update this thread any time with new info and if anyone else has some educated guesses chime in.

Reason: clarity
You've laid out the possibilities pretty well based on what we know so far. We just don't know yet. Based on that leaked engine report I'd say the Z06 will be a return to the C5/6 interpretation of the car... i.e. NA track-focused. 600 horse FPC widebody? Then have the TT DOHC as the ZR1/Zora? Where does the hybrid fit in as the leaked doc had one making 900 ft lbs.
It would we be really super-duper cool if the next car introduced was a Grand Sport with the 5.5L FPC engine making 550hp/500ft-lbs tq.
After than we can get the 750 hp TT blackwing and at the end a ZR1 with hybrid drive making 1,000 hp: 800hp from the engine and 200hp from the twin electric motors in the front.

Do we know that the crank has to be fpc just because the racecar is? We could have a 5.5L DOHC cpc in a GS.
Also GM confirmed the 5.5L FPC engine in the C8.R is not related to Blackwing and we know Blackwing block can't support 5.5L and heads are reversed for hot V turbos which C8 won't have, so I don't think any C8 engines will be Blackwing based, just both dohc and turbo.
Another interesting thing is that apparently a Gen 6 Camaro Z/28 with an LT3 engine that was a hotter NA GenV small block that got canceled. Could the C8 end up with an LT3 somewhere?
Exactly. This thread should never have been started. How many Z06 speculation threads do we have?
You might consider there are some that disagree with you. I, for one primarily visit this forum for news on the upcoming versions of the car. Since there's not much new information out at this point - conjecture, and group discussion is all we have.

perhaps it's time for a Z06 sub-section....
No real info out there yet outside of speculation, but I agree a Z06 subsection would hopefully clean some of this up.
If it's a 5.5l FPC NA engine, I'll sit out a year to see if that mill, as a very large FPC app (for street production FPC application) self destructs with any regularity or displays bad NVH.
If it's a 5.5l CPC NA with good power, I'm in. If it's a 4+ liter FPC TT or a 5.5l CPC TT making big power, I'm in.
FORD COYOTE DEVELOPED FOR P72
It’s a supercharged 5.0-liter V8 tuned byRoush to develop around 700+ horsepower and a maximum torque of more than 825 Newton-meters (608 pound-feet) transferred to the wheels exclusively through a six-speed manual gearbox developed by De Tomaso. The power figures will be attainable with the engine feeding on 91 octane fuel.The Ford engine redlines at more than 7,500 rpm and promises to offer a linear power curve “reminiscent of the purity of natural aspiration” as well as a soundtrack similar to V8-powered American performance cars of yesteryear. The engineers focused on minimizing the sound generated by the supercharger in an attempt to mimic the noise of a NA engine as much as possible and evoke the sound of American muscle cars from the 1960s.
The P72 has been developed as a grand tourer with an engine that will fully comply with emissions regulations in European markets as well as in the United States. A “symphonic exhaust system” is being promised, but De Tomaso says we’ll have to wait a few more months for videos and audio to actually hear the supercharged V8 sing its tune. Using the Ford Mustang GT’s 5.0-liter supercharged V8 as the basis, it means owners won’t have problems getting replacement components since the engine benefits from a solid after-sales support with lots of parts available."
There's an interesting alternative What about a supercharged 5.5 for the C8? If Ford can do it, GM can.

It will be interesting if there is a FPC normally aspirated engine and how it slots in. If displacement is high then you have NVH and reliability issues. If it is highly tuned, then you have fuel economy and emissions issues. If a NA 5.5L FPC can be made reliable, it’s gonna produce less torque than the LT2’s 470 @ maybe 440-450. So potentially slower off the line and out of the corner for extra top end. Not a clear home for it.

Sounds like a really fun engine for the Grand Sport to me. 🤷🏻♂️

I did search and didn’t find a topic dedicated towards the Z06 already but maybe I missed it. There have been numerous side discussions about the FPC 5.5l and some rendering ideas on Z06 as well. Just figured it might help contain the discussion.
<edit: So I just searched again and found a couple more previous discussions. Sorry for some redundancy.>

I would purchase a C8 ZO6 with the largest state-of-the-art supercharger. But, superchargers are just the cheapest solution. The C8 ZO6 deserves twin turbos, and GM can offer it with a C7 ZO6 base price
