Is it just bearing wear ?
about to handle more power before breaking ?
would a 500hp 8k rpm engine last longer with a CCW crank ?
I know that in 2000 HP engine a CCW crank is need to deal with flex. how does it help fix the flex in the crank? would it be needed with more rpms too ?

The Counterweight balances the throw on the crankshaft, by adding weight to the middle of the crankshaft it counters the weight of the rod/piston. LS crankshafts are only 6 counterweight, less cost, less MMOI.
8,000 rpm IMO is fine with Callies 4340 crankshaft, shorter stroke will add strength. Their is a crankshaft company considering to make a US forged full counterweight 4340 LS Crankshaft, which would be a good option next to buying a billet crank.
