Ok great
Hopefully I won't have to do that test but we will see.
Engine makes that noise no matter the idle until the engine is fully warmed. Then it's barely audible. So I suppose it wouldn't be flexplate?

It's not flexplate but could be thrust bearing.
To find out try to move the crank by prying on the flexplate
Ok thrust bearing. Will have to look that one up
It's the main bearings on the crankshaft that keep the crankshaft from going back and forth
You nailed exactly what I was going to suggest. That flexible camera scope is pretty incredible. Pop out the spark plugs, scope the inside of the cylinder and look for physical signs of piston slap. To me, it sounds more like an exhaust gasket issue or a loose rocker arm more than anything else. Ive been down a similar rabbit hole to find at the end of it all I needed was a $10 gasket set or 15 seconds of run time without a valve cover on!
Been busy with work and both kids had chickenpox. What a month. I will see what I can get done this weekend. I haven't forgot. Still got my check list. I did have the Blazer running the other day and after 30 minutes running, the sound was gone.
To be honest I have set the Blazer project aside for the moment. A struggling European economy has not really given me peace of mind about dumping thousands of dollars more into the Blazer. As you know I am American but living in Sweden and unemployment is pretty high at the moment. I am still working and so is my wife but we both work industry jobs and you know how that goes with a downturn in the economy. Industry jobs are hit very hard. The Blazer has turned into a "can of worms" Without a workshop and with little knowledge mechanically speaking, I am at a huge disadvantage.
As it stands right now. The Blazer has to be re geared in the axles, it has 35 inch tires and 2.73 gears which will destroy the 700R4. After it is re geared I then have to have the timing adjusted for a third time because the shops in Sweden are not good at it. The transmission needs to be upgraded to support the HP from the 383. I believe its a pressure spring or switch. Not sure what it is called. Then the vehicle needs a lock up kit installed on the tranny so the vehicle can have 4th gear (overdrive) I have water leakage from the back cab and seals. Ruined the carpeting and padding. I had to rip out everything on the interior. It is like a metal box now. So then I found cracks in the sheet metal where the front seats bolt into the metal. I have to sand down and prime the metal and fix the metal cracks. There is more but at this point It's just one thing after another. If I lived in America i would have already sold it already. I paid 15k for the Blazer and I am looking at another easy 4k in repairs and material.
So for now the Blazer just sits.

Yup, thats pretty much the way it goes owning these trucks. But when thats all done, youll be good until something else breaks..
Iv had mine almost a year and probably put 300 miles on it, barely. I prefer fixing then as opposed to buying them “done”. You connect with the vehicle. Then you sell it and start over

Sorry to hear, but your thinking is right. Economically prepare for the worst and hope for the best. Let the Blazer rest, maybe prepare it for long term storage? Then it’ll be in good condition when you get back to it.
Good luck
Good luck
