i just aligned the crank to the mark on the timing cover and saw that my aem cam gears ,not sure but think were way off.there are to marks accross from each other and another in between those marks with a circle around it(i think its suppose to be the arrow that points up), but this marking with the circle were facing down towards the ground and my car would still turn on but shut off after 10 seconds.i just want to know if this mark with the circle around it is suppose to be like the arrow on the stock sprockets?
