the timing on the crank is proper but with the skunk 2 cam gears i dont know which mark is TDC thats what im asking it has 3 marks 1 is centered at the top above the cam adj. lines the other 2 are on the sides. in the center of the motor how should the timing marks be aligned?? are they to be straight across from echother at the closest point for the 2 or should they be off set?? im new to this whole timing thing and no one arround here knows how to set the timing for the skunk 2 cam gears. everyone tells me to go back to stock cam gears I say no.
