Hello , I am in process of replacing the timing chain set on our 1966 Dart. Motor is 225cid. The original timing chain jumped a tooth and I am trying to line up gears from new set. The Set I bought did not specify. Can someone let me know what marks are to be lined up. I see a dot on cam gear and a dot on Crank gear and figure these are the two to line up. Is this correct? I don't want to make a mistake as this is first time I have changed a timing set. Does the key have any bearing on the location that marks should be in? Thank you for your help. Ed

You have to line the 2 marks up through the centre of both cogs,should have a diagram that comes with your new timing chain set or try to get hold of a workshop manual they show you what to do.

Lining up the marks will get it run. However, due to variations in manufacture of the gears and the crank and cam, you will get best results if you use a degree wheel and set it up according to specs.
