Message	but 120 is way to low. I just built my motor and I'm seeing 150-155 across all 6 cylinders and I have the most aggressive cams, which have more over lap. Also are you performing the test correctly? Meaning removing the throttle body inlet pipes, balance tube, and turning the engine over with full throttle. It makes a huge difference if it’s not done Right.
