Here’s the owner telling us in his own words about the failure at only 621 miles :

In this video, the owner claims of what was going on with the car when the failure happened, and the incident is backed with video from just happens to have a GoPro already mounted which captures the moment the engine crapped out. There’s also a photo they took of the dash as the engine failed and the oil temp was only 154 degrees.
I did a slight pull from first, second, third. (watch the start of video)

The street kind of veers to the left, then I get back into the throttle for a bit, and we decelerate to a stop sign, and as we were decelerating, we heard a clunk, clunk, clunk, and I couldn’t believe what I was hearing.
Since we were so close to Jay’s house, I pulled a U-turn and the car locked up.
So, we got a scan tool, and [it showed] misfires on one, two, seven, and eight.

At this point, the owner details his break-in procedure for the car, claiming it was essentially babied during that first 500 miles, and he was always diligent about warming up the engine before driving and keeping the revs under 5,000 RPM.

According to the owner, General Motors and City Chevrolet provided outstanding service to address the blown motor:
We all heard about the customer in California, and they talked about two months or so to get his car fixed, get a new motor.

That customer from my understanding kept the car. GM, I’m super blown away. I thought it was going to take two or three months.

I have a full track schedule ahead of us and within a week of the car being dropped off at City Chevy in Charlotte (shout out to those guys Ricky and Jeremy, those guys did an awesome job keeping me in the loop) so literally, two weeks to the day, a new motor is in the car, and we’re starting to put breaking miles on the car again.

Anyone believes, babied, race camera already mounted, his full race scheduled, and he is a good boy :)

Update,
Owner beating his chest in cyberspace :

I have a full track schedule this year and will be putting the car through some reliability testing! Ha!

I have tracked a lot of different cars from Vipers, Porshces (992 and 991.1 GT3), GT350R s, Rush SR ZLEs and I will do the same safety and modifications to the Z06. Already have Forgelines and Hoosiers and will be upgrading the brake pads after the stock ones wear out. Most likely going with 2 piece Girodisc.
I do plan to run a roll bar and harnesses as well.

If I have a failure on track, and it's not covered - I'll let everyone know, and I'll get it fixed on my own dime and keep moving forward.

As far as my track times at VIR - you can look up some videos on YouTube. 911SLO has some of my GT3 running 1.59s. (1:59.12 is my best).
Have run 2.00.xx in a bone stock ZLE. 2:01.xx in a GTC Viper a couple of years ago.

So people still think he babied his C8 Z06 ?

Reason for LT6 engine failures ?

"During the development of the LT6, the engine team found hot spots in the main bearings that it attributed to cavitation near redline when the oil thinned out at high temperatures.
To combat that, the Z06 has a number of heat exchangers up front that keep oil temps below 200 degrees."

Amongst his mistakes he says he starts the car with remote start and leaves it to warm up at tickover. Great way to knacker any new car engine, especially a high performance one. And then some "pulls" in low gears - brilliant.

Even base C8 driver manual says,
"For the first 500 miles avoid driving at any one constant speed, fast or slow, including the use of cruise control."
"For the first 1,500 miles do not participate in track events, sport driving schools, or similar activities."
