Yep i rotate CW, my cam gears are correctly labeled too, I checked this as I was worried as well.

Ill take another read though the posting too.

What if I were to do it in two steps, shifting the cam events +4 degrees advanced (Intake +4 and Exhaust +4) then took the next step of lowering overlap (Intake +4 - 1 = 3 Exhaust +4 + 3= 7)

Would this theory work (+3 intake, +7 Exhaust) or would the ideal be more like intake -1 and exhaust +7



After all this messing around I assume resetting the base timing is a good idea, its triggered by the intake cam so Id have to adjust my ecu (standalone). Would any of the cam timing changes warrant advancing or retarding the ignition?


I'm starting to lean towards running +4 exhaust and leaving the intake at 0 so i wont have to redo my timing, and seeing if I can notice a differnece, or maybe try +6 ex and +2 intake giving me a +3 shift and a +3 ex / -1 intake

Sorry for all this mindless thought, Im slightly thinking out loud , hopefully it makes a little sense
