Sorry but there is no way in hell that did not overheat. Either that or you ****ed timing up real bad and it detonated, but theres no way it will do that at idle.
Im gonna have some ***** and say its your fault. Sorry.
Never said it just idled....I had it out and hit hard a couple of time, but never got over 50mph.
Yep, it may very well be my fault, and I'm willing to accept that.
Rut Row......good think I still have my 350 block. Looks like I may eat this puppy. To be honest, the damn uncapped headers were so loud, I couldn't hear if was detonating or not.....
Dayum.....
Don't be so sure on this. It could be a bad piston or something else. You would really have to detonate it hard to break a piston. I'll bet the wall is cracked in that hole also.

It seems like the pressure cap would have given way and would have been spewing fluid if it had overheated enough to do that type of damage. Assuming it's functional of course.
When you get it put back together, buy some exhaust flex tube and some clamps from autozone, then hook your headers up to the rest of your exhaust. As fun as it is to run open headers, you want to hear internal noises of a brand new engine.

Never steam, or dropped any fluid. Did not go over 210, and my gauge appears to be accurate.
I don't see how he could have cracked a cylinder. That would definitely be a warranty item.
might as well rotate the crank and see.
setting your timing wrong and driving the car is definately not covered under any warranty. Im suprised that all the valves are there? Any chunks of piston layin around in the garage?
I'm thinking defect here....seriously, the timing would have to bad enough that it would have been noticeable. Remember the plug is clean as a whistle like it hasn't fired, or very very few times.
I did not put a timing lite on it. Guilty of that, but it cranked on first start and will backed it down to get the idle rpm set right. I had it idling at around 900 rpm. It was considerably faster before we backed the timing down by playing with the distributor. The timing could have been a little fast, but I wouldn't think it was that much off.
Maybe someone will learn something from this....I sure did.
Good news is I still have my original 350 block, can reuse almost all of the parts, so I just build the biatch back even stronger.
I must say, that sob had some serious power, and that 1/2 mile run was more joy than I have ever had in the vette!!
So we move on......
I'll let blueprint make the call, and will talk with them in the morning. But I think there's a good chance that I'll loose any fight. Probably don't have a fight.
As I think I'm going to have a few more than last night!
I would not give up that easily. Your timing would have to be way off and probably would not idle very well if it was that screwed up. It will be their decision but put the pressure on them.

Also notice the top of the piston is much cleaner than the others, of course both it and the plug probably got a good washing with very hot water!!
You're a lot braver than I am. How much did you spend on that motor? I think a cheap timing light is $30, and an adjustable one is $60 at Sears.
Got a cheap timing light....doesn't work real well with semi lumpy cam. I "thought" we had it pretty close by ear, and it ran like a bat out of hell with a good strong idle.
hold on a minute. Don't give up yet. I've never seen an engine grenade so fast from advanced timing. You should have heard some clattering over the exhaust.
What if we got the order of what happened wrong.
what you're assuming now.
1. Timing was too far advanced.
2. Broke piston.
3. Piston chunk cracked cylinder or head.
4. Water got in oil.
what if:
1. Engine cylinder or head leaks coolant.
2. You get hydro-lock and bust the piston.
From: Who says "Nothing is impossible" ? I've been doing nothing for years.
Don't throw in the towel yet, let them make the diagnosis, if you start blaming it on yourself at this point it will be almost impossible to reverse that if something is found that makes it look like their mistake. Just do as they tell you and don't offer any more info at this time. It is still up in the air as to what happened isn't it ?
Still haven't answered my question about any RTV present around the water passages, looks like that milky stuff leaves a trail right to the water ports on the underside of the intake
1. Engine cylinder or head leaks coolant.
2. You get hydro-lock and bust the piston.
Hydrolocking is more prone to bending rods than breaking lands as far as i know. Plus to really hydrolock it that bad ther car would die and just about stop in its tracks. Im really surprised those valves are ok. Any close of pics of the bottom side of that head?
