I have a 72 deville 472 motor yesterday i noticed my distributor didnt have the vacumm line on the vaccum advance so i twisted t a lil to get line on. Now the thing turns left and right is this suppose to do this or is there a way i can stop this and tighten something up to get it to stop?

It seems that you have not tightened well the screw on the plate fixing the distributor on the engine block. It should not move at all. You have to find the correct position to get the correct timing and get the distributor fixed on that point.
