Actually. And I am not just saying this. The factory rockers are amazing from 2001+ and everybody uses them, reliable even at 1k rwhp with stock pushrods and heads.
The trick like most engines is using low lift and gentle ramps.

Be reasonable with RPM. 6000rpm is practical for almost any 02+. I might take a 4.8L which is a de-stroked 5.3L to 7k frequently.
The G's without oil problems is in the oil pan. So many simply fill extra 2qts of oil when drag racing. others and especially in swaps use a custom oil pan, the sikky unit for example has a trap which only allows oil back to the center pickup and not back out to the edges of the pan.

Want turbo LS ? go cast iron truck block.

Actually the fastest turbo cars use the Aluminum L33 engine more than anything else. It holds the record I am told

Finally, Here we go: 6L, stock bottom end with a cam and springs. Factory rockers, pushrods, lifters, pistons, crank, rods, balancer, oil pump, head gaskets, coils, bearings have 200k or 250,000 miles I forget which.
1000rwhp dynojet from that ^^
