Ive been told that when im near shifting, my car blows smoke out the exhaust. I don't notice it because my rear window is tinted.

I am running a torquer v3 cam, prc duals, hardened pushrods, full boltons, etc.

Limiter is set @ 6800 but i usually shift ~6500 if im racing.

Im gettin 12.5 a/f ratio at WOT.

Anything to worry about? Ive watched vids of me at the track and i honestly dont even see any smoke in the vids (this was when a couple people said something).

Depends on what color it is.

Fuel would be ok.... Oil would not.

If it's oil, you could have PCV issues at high RPMs and would need to see if you wanted to replace a defective PCV or convert to the LS6 PCV system.

what color is it? i think the only bad one would be if it was blueish blackish

I am not sure on the color. My one friend said I was burning a bit of oil at high rpms so I am thinking it could be a pcv issue. If i rev the car parked i get a little bit of fuel smoke at the high rpms, that's all i notice. What exactly is the problem with the stock pcv system (I have a fresh valve as of last year so I don't think that's the issue) I keep hearing people doing upgrades but what is the purpose?

Stock LS1 PCV system draws the crankcase fumes from the valve covers where there's a lot of oil mist. This can cause some oil consumption and octane degradation.
LS6 PCV system draws it's crankcase fumes from the valley under the intake where there is very little oil mist.
I converted to the LS6 system and added a catch can to the system.
