What was it then?
If the OP wants a built block and the shop will "work" w/him w/o accepting responsibility, then maybe its a fair deal. If the OP pays full price for said build, then I find that problamatic. Just paying him to fix the engine, still leaves him a stock engine. But doing a build for him @ a $4500 discount w/o accepting official responsibilty is a differant story.
So I have to ask, which one is it?

If the Op hasn't mentioned whether it was coolant or gas how can you possibly come to that conclusion?
The inj need to be tested either way by someone else other than the manufacturer. If the injectors do have a problem you don't want them in the new engine.
When the the plug was pull on the pan it would have told what locked the engine. If coolant, it settles at the bottom and they would have seen water drain first before the oil. If not coolant it was fuel. In this situation coolant is more likely. It takes a good bit of fluid to bend a rod. Coolant is more likel to fill a cyl while the car is off than fuel. Even a stuck injector will bleed line pressure after key off, and the key on. But not much fuel from a fuel pump prime UNLESS it primes to a target psi. Then you could have a probelm.

Trying to blame a bad head gasket although the car drove in and fine previous to the injector change is highly unlikely vs the event that let up to the hydrolock and bent rod.

I've seen more bent rods from coolant. It has to be a good leak to misfire or smoke. I've seen them leak and pass a hydro carbon test. But blows the rad cap under WOT. The last one that did it at my shop showed no signs what so ever. One before that, the only reason I knew was I popped his radiator after 10 seconds of running and the cooling system was pressurized. Passed hydro carbon test as well. Leak into his engine. That cyl looked brand new. Plenty plausible. More u likely is a rail leaking into a cyl on an injector change. I that was the case it would have locked first crank after install. Not multiple starts. It's all pretty far fetched but something locked it up. Thing w a bad injector is it would have to be keyed up multiple times before a start to get enough fuel into the cyl to hurt something.
I'll have to go back and reread, but could of sworn op said they pulled it on the dyno, shut it down, changed the injectors and locked up on the attempted restart, not multiple starts.
I've also had all kinds of head gasket concerns, but there was always something else to go with the HG concern. Either blowing radiator, blowing out of or cracking reservoir, loss of coolant, misfire, smoke. They also haven't just happened over a hour time span with no other issues and enough coolant loss to hydro lock a motor. There would of been misfire problems upon start ups, with smoke and hard cranking.
For the shop having no issues starting the car and being a hot restart, then pulling it on the dyno and then locks up, just doesn't add up

A hot restart would lead me more to coolant. 16 psi trying to push coolant into a cyl after key off.
Most all the cars I've worked on over the last 15 years have been classics. Not driven much the coolant consumption is hard to see. Idk, I just don't think because it was in there possession last makes them responsible without proof.

I don't know. I've said what is the most likely cause of the failure, within the time frame, and work that was performed. If people choose to believe otherwise, then be it. I know its hard to prove without proof, but with all the info and facts of the situation, its very hard to prove something else caused a bent rod. I'll leave it at that, and hoping for the best to the op. I'm out of this thread.
It was fine on the hot restart when he brought the car, then it was moved to the dyno and next start after injector change it locked up.

The shop has not tried to BS their way out of anything. You're jumping to conclusions here and your comment is on the verge of slanderous.
LMAO! Bastard. :lol:
Ive only found 2 threads on different forums regarding a seized motor issue that people have posted. Both were stock and locked up while driving.
Early on in this thread it was stated a local ford dealer to the shop said they had experienced a handful of cars in with that issue.
taken from the two threads i found:
There is some SERIOUS, HARDCORE nutswinging going on in this thread trying to say its not the shops fault. Geezus. Do you people work there or something? I didn't read the whole thread because I don't have time to rummage through all the BS.
Here's what I am gathering after reading the first page...
1. The car was fine
2. Cams get installed -> Car breaks
How is this not the shops fault????????????

Thanks for the info..I still find it hard that this is a ford issue as this is the 1st I've heard of it.
You need to re-read the thread. That is not what happened. Try coming up with some adult venacular of your own rather than the usual internet jargon of that a teenager on Facebook. Swing on that.
Trust me I'm not wasting my money but thanks for caring.
