Good point. I personally don't use timing marks to time my engines but if you want to ensure your mark is accurate you can pull out the plug in #1 cylinder and either use a TDC tool (if you have one) or even feel for TDC with a heavy wire or plastic stick while someone turns the crank slowly by hand. warning: Don't use anything that will break off or damage the piston or spark plug threads if it binds. (don't use a screwdriver in other words)
Once you are sure the piston is exactly at the top of it's travel, look to see if the groove on the balancer lines up with 0 degrees on the timing mark tab. If it doesn't and you're sure you're at TDC, your balancer may have wandered.

Subject: RE: [Chrysler300] Ignition Timing
As the rotor turns counter-clockwise during operation, one must turn the distributor body clockwise to advance the spark. Previous posts suggest it is not always proper to accept the timing marks on the crankshaft due to possible rotational shift of the vibration balancer.
Which way (clockwise or counter clockwise) should I turn the distributor to advance the ignition timing on my 300F? Terry McTaggart
