    So Im setting the timing on my truck but I dont know where the TDC mark is on the Timing Tab. Is it right in the middle of the tab or is it all the way to the right side? And is it the point or the valley that the timing mark needs to line up on? I cant read the timing tab to figure it out. Anybody know?
