Are you saying you rotated the crank that much without ANY observed valvetrain movement? Since you're looking at the timing mark, will assume you still have the timing cover installed and are referencing rocker arm/pushrod movement with the valve covers off or something like that? Or perhaps just the distributor cap off and referencing the rotor tip? Just curious. If that is the case, then yes, time for a new timing chain. Recommend a Cloyes true roller. Not expensive, good quality.
