The wiring harness that goes behind the intake is a bit melted, but I don't believe the wires are damaged-- just the black outer plastic.
The Knock sensor wires are completely gone.
And there are pieces of intake down in the heads... not sure if they've caused damage yet.

What about a fuel solenoid leaking? I saw something like this on an ls1 car one time with a wet kit but the car burned to the ground. They finaly said some thing to the effect that the fuel was puddleing in the intake and caused it to happen. This happend when the car was leaving the line. I wouldn't think this would happen though if you were in 5th gear at 50 mph or so. I have definetly heard of problem with fuel puddling in ls1/ls6 intakes though.

The Facts:
1. Nitrous was NOT armed.
2. Nitrous bottle was CLOSED.
3. I was in 5th gear at about 2800 RPM
4. When I increased my speed to pass another vehicle, the engine backfired VERY loud.
5. WOT was never reached.
6. The intake is now blown apart on every runner.
7. The upper and lower lid are also destroyed.
8. I have been told this could be caused by a lean condition.
9. Any other internal damages have yet to be discovered.

This would be my guess. 2800RPM in 5th gear would be lots of load and not a whole lot of air velocity in the intake. If the fuel solenoid were to start leaking and puddling up when you were cruising along in 5th, and then gave it a decent amount of gas and put a lot of load on the motor....POP!
