But completely tearing a block down and looking at the components can definitely give you a good idea of what you've got. These guys build engines. They should know what these things look like.

what does it look like? it's just a lump of metal. how can anyone tell by "looking" how durable an engine is?

Just in case you aren't being facetious. Those with many years of experience with building high horsepower applications can just look at that lump of metal and give you a good idea of the durability of said lump of metal.
I would imagine (because I am not one of those people) that you could tell by checking the thickness of the higher stress areas and where the block is braced or ribbed.
Take for instance the small block chevy, there are some blocks that have only two bolts on each main journal that holds the crankshaft in place. There are others that use four bolts on each main to hold the crank.
Which do you think would handle more power?

This is absolutely true, but ultimately a limit isn't known until it's breached at least once.

I'd just be happy to know how meaty the OEM piston ringlands are... that's usually the first thing to break even with an otherwise good tune.

Yep. And it will take a few people breaking stuff to identify the true weakpoints of the motor.

Contrary to popular belief there is a lot of stuff inside that "lump of metal."
