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?
