Well, the dry sump engines have a forged crank vs. cast. Better? Basically yes. Does it mean anything if you aren't racing or adding HP mods?

Same crank as is used in the 638 HP LS9, except for the number of bolts that attach the flywheel.

The weak link is normally the pistons when you push the engines hard. 100-150 additional rwhp can be very reliable. Reliability and longevity very much depend on how you drive your car though.

Last month's Hot Rod magazine had an list of what breaks at what power level on the LS3. It said the cranks are good to about 900 flywheel HP. Just about everything else will go before the crank.
