I stayed stock stroke with my LS build for most durability on the street. The longer stroke will force the piston further out of the bottom of the cylinder than a lot of people like and could reduce longevity. The longer stroke also pushes the wrist pin into the oil ring land.
A happy medium is a 3.9" stroke crank. 4+" stroke cranks have the issues above. 3.9" is the biggest without the oil ring issue.
Stock LS6 will handle up to 700 hp without issue. If you're looking for over 600 that's when you should really invest in forged parts.
