Installed SC and blew the engine
Well I took the week off work and installed a Procharger kit on my Z06. I started it up for the first time on Friday and it seemed to run fine. I drove down the road a little further and never got above 3500 rpms. All the sudden my car shut down completely. All the power went out so I assumed it was an electrical problem. So I had it trailered home and replaced the battery. It had power again, but it wouldn't turn over when I tried to start it.
I jacked it up and oil started pouring out of the oil pan on the drivers side. I'm guessing a rod made the hole, but I don't see how that's possible since I didn't get over 3500 rpms. I'm sure it's not related to FI. What are my options here? Does anyone have a used LS6 short block for sale?

Sorry to hear about your troubles - that definitely sounds like an installation issue.
As for options - that really depends how much damage was done. Worst comes to worst you put in a new forged bottom end, for under $4K.

That looks like hydrolock. If it was a rod you would have a nice round window in the side of the block. You can't compress water.
Has the car been losing coolant recently?
It doesn't take much water to do that to a motor.
You can pick up a new LS6 block with forged rods and pistons for a decent price.
Good luck.

Here's the other side of the block:
Drivers side hole
The car hasn't used any coolant that I know of. I never saw white smoke either. When it happened I kept looking in my mirror expecting to see a rock or something emerge because of the noise/feel.

Know matter how much boost you have it set for if you did not exceed 3500 the damn thing had not spooled up much boost anyway and at 3500 I am not sure how much on the boost side of the gauge you were at, this reminds me of my motor when I hydro'd one in a rain storm in a deep area in the dark--I had a rod come through and knock of the starter it was so bad, I don't really see how this happened but will be very interested in knowing when you find out, I agree with you that this is a bit of a mystery--

It was a P1 Procharger, but my boost gauge never read over 2-3 lbs. I don't see how it can be boost related. I installed a cam at the same time, but used JPR lifter holders so I'm sure a lifter didn't fall. As far as I know it wasn't using any coolant either, so hydrolock probably didn't happen.

no way at 3500 you were making enough boost to do that. How hot was it out side? What octane gas were you running. I think a piston would let go due to detonation before the block would. Id say to look for the cause elsewhere.
