Dunno why this is a hard concept for you.

I'm just making up HP numbers here but let's pretend a stock LT1 block is capable of safely handling 600HP and beyond that it may last 1 pass or it may last 2000 passes... Either way it's a gamble each run.
Now let's assume you buy a rotating assembly that is capable of handling 1200HP and put it inside this block... What is the point? Regardless of how much HP your crank, rods, or pistons can tolerate the fact is you still have them in a block that is unsafe at half the HP level the rotating assembly is. Therefore you might as well just buy the cheaper stuff that is rated around the same limits as your block because you are simply wasting your money. The saying "a chain is only as strong as it's weakest link" applies here.
I'm not saying you can't go fast with stock parts - I and countless others have done it on a somewhat reliable level but it's still a gamble each pass
