i am confused!!!!! i wanna know why the skunk2,crane,and dc,ect are backwards compared too the aem cam gears .. the reason why i say this is because on the skunk2,ect the + sign is on the left hand sigh and the - sign is on the right hand side compared too the aem cam gears the retard is on the left hand side and the + sign is on the right side. so are the skunk2 correct. and too advance the cam would be clock wise and too retard would be counterclock wise

 

It just depends on which part of the gear the numbers are written on. The could be on the outter part that turns with the belt, or the inner part that is bolted on to the cam.
