guys with turbos and the z06 cam with truck manifolds what rpm are you shifting at and how is your cam installed? mine is advance and doesn't want to pull past 5900 rpm.

 

i think i have Lownslo06's shifting out at 6000 and it pulls awesome.. its installed straight up.

 

what size motor? mine pulls strong, but it seems soon as it tries to pass 5900 it really falls off. i shifted it at 5900 and it pulled way better.

 

I think I am going to be shifting right around 6k as well. I shift out at 5800ish right now on my stock cam, but my 67/81 falls off around 5300-5400. Once I upgrade and put the LS6 cam, I think it will pull decent to 6k

 

I have the 6.0 and shifting at 6k 1-2 and then 6200 from 2-3. Idk about wot into 4 cause i don't do nascar stuff! But it pulls great and never falls off!

 

so mine being advanced and pulling to 5900 is about right then. i do have to say it pulls hard. its a little harder pull now with 100* iat and 13* timing as the stocker with 70* iat and 18* timing. so when it cools off and the timing goes back up it should be sick!

 

That sounds about right you are on the right track! Just wait for cool weather haha, like me!

 

i know its doing something for sure. the turbo is louder now so i think its working harder. stupid hot humid weather sucks.

 

i guess i dont understand the concept...... why advance a stock cam? Does it benifit any way or what?

 

well people install it straight up and dyno shows drop in low end torque. the z06 pulls to like 6800 rpm which i don't need. and the truck intake has been basically proven to not like to pull high rpms either. so i figured i would put the cam where every thing else agrees in rpm. the cam feels like stock down low but when boost comes in it really kicks. it just falls after 5900 rpm.
