Well, the Schrodinger's cat analogy is pretty accurate. You won't know what is alive or dead until you open it up and check.
I'd also guess that you won't be able to get by without having your journals polished at the very least. You need to pull the engine and take pictures as you tear the whole thing down so you can prove to CHP what failed and why.
Just for curiosity purposes (don't kill the cat) what type of oil was used on the break in and the two oil changes after that? Any additives?
5w20 is probably what killed it. These engines aren't designed to run on that, the clearances are too wide. I built a 302 for a friend of mine a few weeks ago and tried priming the lifters with the engine on the stand. All I had laying around was 5w20, so I poured it in to prime with. That chit was SO THIN, those hydraulic lifters bled off and refused to prime. Dumped it, went and bought 10w30, and they pressured right up. Crazy. Don't run 5w20 in a push rod motor..
Well, if for nothing else other than to find out what happened to the OP's engine,..(cause I assume that he's pulled it by now)On your first few pictures of when you took your distributor out and you took one of inside the hole, the metal above the cam was chipped and I'm wondering if this is a problem? I have a 302 I acquired and it's a project but it's not bad except for my metal above the cam is also chipped like that and Im wondering if it matters or not, and what it's for, if anything?
I've included a picture of mine

The factory casting process leaves all kinds of divots, slag, and rough finishes everywhere. If there was no need to machine a part of the block after it was cast, it's left alone. Areas of slag may have been "chipped" off at the factory for the sake of needed clearance. The fact that your engine and this one look similar is a testament to that "necessary clearancing".
It will be fine,the distributor is supported up top with a hold downI had a buddy say that it could be to hold in the distributor when it's running harder at high rpms and I personally do not think that's what it's for, but what do you think? Will my distributor be held in just fine or not?

The distributor is held in by the hold down....... it has a bolt....
