All chevy engines including dodge have the same fireing order 1-8-4-3-6-5-7-2 and dist cap rotates clockwise ford rotates couter clockwise and has a different order 1-5-4-2-6-3-7-8 the reason you see #1 and #8 pistons at TDC is that one is on its exaust stroke and one is on compression stroke. hope this helps FORDMOTORHEAD
