I need more info on this because I'm not sure I understand. First, I think the cam that is in the engine has a firing order of 1-3-7-2-6-5-4-8 instead of the older firing order of 1-5-4-2-6-3-7-8. But lets say it has the older one. If the air/fuel is already traveling to 7 then 8 opens wouldn't 8 actually fill better than say 1 would because the air/fuel is already being sucked that direction? For 1 the air/fuel has to change direction from the back driverside to the front passenger side so wouldn't 1 get less then 8?
