Depends on the valvetrain. I have bounced off a 7100 rpm rev limiter several times.

6200 rpm is the rev limiter stock, and 7000 rpm is no problem with the LS1. It's a good idea to run 6 qts of oil and make sure to check the oil level frequently.

You might want to throw in some rod bolts. Stockers like to break when frequently spun high. Small price to pay for one less thing to worry about.

Depends on a lot of things. 1997 - 2000 had weaker rod bolts. I wouldnt spin those past 6500 or 6600. The 2001 + had stronger rod bolts and I routinely spin mine close to 7000. Upgrade the rod bolts in any yeah, and it shoudl be pretty stout in terms of RPM.
