2001 Chevy 6.0l gas torque curve?

I don't have the tq curve but the previous pic someone posts looks close. I have own an 02 and can tell you that what your pulling it won't be an issue. Pull in 3rd and it will kick to 2nd on the hills. Power is found 3400-4400 and it can rev around 5000 at times but won't hurt it. My 02 had 180k plus on it when I traded up to the newer version. That 02 had been worked basically everyday of its life. Incredible engine cause it never needed anything and had been abused prior my ownership. I bought the truck from someone who knew nothing about maintainance and worked that truck pretty hard at times. Regardless I bought it cheap and used for for several years. We checked the compression and leak down at 180 k and it was still within factory specs... Really surprised me since knowing the history, so it made a believer out of me on these GM 6.0 engines. Hence I bought the newer version and never have regretted it....The truck will use higher RPMs but like stated before, it can run all day in that range with no issues.
