Is it toast?

Fair enough so shouldn’t be to difficult to turn over once all the plus are pulled even if it’s hydrolocked 

If you take out all 8 spark plugs any water or fuel should spill out when you turn the crankshaft over as you will have eliminated all compression by removing the spark plugs.  If it won’t turn over something serious is in play.

Pull the plugs, then with recharged battery it should spin easily.

Let us know,

Scroggins Dickey handles GM crate engines and are in Texas:  https://sdparts.com/

If you go a non marine supplier route make sure you are getting a marine version.

Would you know if they have any marine version or what numbers to look for?

Might be worth seeing if there was any sort of warranty.  Seems odd to have a failure on a 5.7L in only a year.

How did you spot a dropped valve with a bore scope? Did you pull the valve cover to verify?

[MoonDawg]

I would pull the heads and check the piston...if there a little smile on it, I would just get a new valve job. If there is a lot of trauma going on like a hole in the piston or gouge in the cylinder wall then it might be time for a new engine. 

[williemon]

Might be able to just pull head and have valve replaced if the pistons not damage.

The only time my engines have been toast is when a piston rod comes flying out of the pan...5.7L are famous for oil starvation on the crank. My Malibu has not had a problem with that but In the 80s I had a jet boat that went through 3 oil pans.
