318 tuning question

it will run with the wires any where but that means the distributor isnt set in correctly. for example if the wires are moved one tower over on the distributor that means the distributor is a tooth off. you also would run out of timing ajustment as the vacuum advance pot would possibly hit the intake etc. as for how far the rotor moves that is a loose measurement what that shows is timing chain slop. i would say a half inch is good if more more id suspect timing chain wear.
