The 09 G8 has the base engine I want to use in my next build. A 12:1 compression LS3 stroked to 6.7L. I am trying to learn as much as I can about its DOD, VVT systems before I start the build.
I will use VVT, have a couple different plans on how to control it.
Not sure about DoD yet. I would like to use it but not sure how.
The LS3 doesn't have the DoD. The L76 does. Basically it is an LS3 with a different cam that won't break the DoD lifters.
