The most common engines in the 2013 Chrysler 300 were:
* Pentastar V6 (3.6L): This engine uses a dual overhead cam (DOHC) design.
* 5.7L Hemi V8: This engine uses a pushrod design with two camshafts, one for each cylinder bank. It's not technically an "overhead cam" in the same sense as a DOHC engine.
Therefore, the answer depends entirely on the specific engine in your 2013 Chrysler 300.
