Stock LS rod bolts give out around 7000? That's the weak link in the rods. With the ARPs, you have few worries revving to 8000 or higher.

Of course, if I'm mistaken, someone please correct me.

 

8500 for 1.5 years/ 15,000 miles with no problem. I retued with new parts and i've started revving to 9k. OEM LS rods shootpeened with ARP rod bolts. I could probably rev higher but too risky.
