I have not asked. He supports what I ask sence he knows I won't hold him responsible for what I ask.
I'm leaning towards the 3.4 at 6500 rpm a after seeing the boost ramp looking like a twin screw. I am starting it with the 3.9, but only for initial testing.
I just realized that the 3.9 would be slower spinning then the 3.4....... Brain fart. it's been a crazy day..
