Oil film thickness at high rpm is another mater. The only way I know to improve that is to run higher oil presure. Some race engines run 120 psi.
The GM engineers that designed and tested the LS1 said the low end is good for 7000 rpm continuous all day. Above that oil film thickness gets a bit on the thin side.
With some improved rod bolts, an occational rev to 7200 rpm is no problem.

Lack of oil is probably the most common cause of the death of LS1 motors. They use a lot so you have to stay on top of the oil level.
I’m paranoid about it too after the last time I tore down my engine. I found one scratched up rod bearing, and it was the last one on the oil galley. All the others looked perfect. My shift light is at 6800, but rev limit is at 7000.
