That sucks! What are your plans to replace the engine?

Glad to know that you are safe, and good luck getting it back together.

Sorry to see you join our club. 
How many track days do you think you had on her? Mine went with 87K and 30+ track days.
What oil?
Do you short shift or let her wind out to 7K

Engine Blew at HDPE
Do you know that a valve has dropped yet? The reason I ask is that this looks like the kind of track that can cause momentary loss of oil pressure in an unmodified pre 2009 Z06, and I think that either dropping a valve or loss of oil pressure could result in a hole in your engine block.

Posted in your other thread, but if you are still running the stock oil tank, looks like you were in the oil starvation prime zone as you were in a sustained left hand turn for 20 or so seconds. 
Keep us informed of what you find out. Sorry for the bad luck....

Mine is stock 2006 (except for a Killer Bee intake and a Halltech tune), and I dangerously ran up to 6,500 to 6,800 RPM regularly, and bumped off the rev-limiter once (after getting slowed down a little bit by another car, I was real close to the brake zone for the Bus Stop, and I just kept my foot in it and ran it up in 4th gear to 160 mph and an instant before braking it bounced off the rev-limiter).
Sometimes I'll shift into 5th early (around 6,000 RPM), but most of the time I would run 3rd and 4th up to in excess of 6,500.

"My Engine Didn't Blow!?!?!?!?!?!?".
Two years later, he's posting this one up.
and it was also the first thing I thought when I looked at his video, at that 1:16 point and on that he makes mention of in his other thread.I had seen where he had run this track in the past and you can get an idea even looking at his avatar that he tracks the car and has made long left handed sweeping turns in it.
Previously he had posted up this with regard to the oiling issue:
I have a 2006 Z06. The early Z06 came with a 7.5 quart dry sump tank.
If you didn't get a "Low Oil Pressure" message in the DIC then I don't think you have anything to worry about.
I run my Z06 with about 7 quarts on the track - anything more than that and it starts to blow it into the intake and can cause problems.
The early 7.5 qt system could have problems when running a track with a high speed left hand sweeper where you generate more than 1 lateral G for in excess of 4 seconds.
There aren't many tracks where that occurs, and my car has many laps around the left hand turns on the Daytona banking, but the lateral G load bounces around from 0.5 to 1.0, so because of the banking I'm not sustaining >1G and have never had a problem at Daytona or other tracks I've been running.

It will be interesting to see what his report on what his heads look like when he removes them

This was really an ironic thread in that two years ago, almost to the day, he had posted up that last thread, and the title of it.

i understand but Bob is a friend of mine and putting salt on the wound is uncalled for. not only did he post it once but in another other thread. him digging up a thread from 2 years ago to laugh at him is uncalled for and i don't regret with my previous statement.
