It'll be a day or two before the shop do a complete tear down of the engine.
Any update?

Yup, it was a bent rod. I'm sure he will post in here at some point. He is going to build a new shortblock now.
Wow, that's no good.. Bent rod from hydro lock, or just unexplainable miss fortune?
It is a known fact that there have been many other 5.0s coming into Ford dealers on completely stock motors with locked up engines due to bent rods. The shop even called the local dealer and they confirmed that they have even seen some in person.
To me it sounds like a weak rod material somehow...especially with the power level he was making. It was only a matter of time, and all the other cars did the same around 5k miles as well.
Jeff will chime in eventually with more details, as I pulled most of this from memory from our local forum.
So whats the proper way to upgrade injectors?No offense but I have not heard about this from anyone in my dealer connections and have not seen it at work.
Not saying it was due to the injector install but takeing off a couple injectors and letting all that fuel fall down in the cylinder can easily hydrolock a motor.

It's easy to hydro a cylinder when swapping injectors if you're not careful. Not saying they did, but it could sure happen.

Take the fuel rail and injector assembly off the car and over to the bench. Removing an injector lets a lot of fuel out, potentially right into the open hole directly beneath if done on the car.
