The bottom ends on the LSx-based engines are pretty stout. Shifting at 6000 or a little higher won't be a problem. However, as you approach 6500, you may want to consider upgrading your rod bolts. They are the weakest link.
Well my Yukon denali has a Lunati cam and when I have the snowmobile trailer on the back with 4 sleds. On the interstate with the cruise set at 70mph it will sit at 5700/5800 and not shift till I crest over the hill I am on and there are some long and steep hills when I travel thru the PA mountains. That engine actually spun a rods bearing with 42,000 on it ? I put the cam in at 13k ?Originally Posted by DBRODS
As for the durability I know what they will take alot of abuse. I have a turbo GTO with a stock 6.0 with a 90mm front mount that makes 770rwhp and my 2000 camaro that has a 418ls3 shown in my avatar 9.60's N/A 135mph . I just feel horsepower from RPM's is far harder than nitrous and blowers as they are compressive loads. Just wanted to know what others are spinning with daily drivers ? Just because a couple people can run there engine 7500 doesnt mean its the right thing ? I like to take a consensus and make my decisions....

Damn! I don't think I could ever do that to any of my vehicles. I get nervous when my brother cruises at 3500 rpm in his 5.3 Chevelle. WTF!
Big slow mud truck with a TUNE!!!!!!
I would spin the 5.3 in my brother's Chevelle to 7000 rpm, if the tune would allow it.
