Timing mark order on an Dodge Dynasty 6 cylinder?

The firing order for a Dodge Dynasty's 6-cylinder engine (assuming you mean the Mitsubishi-sourced 3.0L V6, the most common engine in that model) is 1-5-3-6-2-4.

However, it's crucial to consult your specific vehicle's repair manual. Different years and even slight engine variations within the same year could have subtle differences. The manual will have a diagram showing the exact timing mark locations and their relationship to the crankshaft and camshaft sprockets. Improper timing can seriously damage your engine.
