To determine the cylinder number, you need to:
* Know the specific Hemi engine: Different Hemi engines (e.g., 5.7L, 6.1L, 6.4L) have different layouts.
* Consult a service manual or parts diagram: These diagrams will show the cylinder numbering for your specific engine. The number is usually cast or stamped on the engine block itself as well.
In short, there's no generic "cylinder 1 is always here" answer for a Dodge Hemi. You must consult your engine's specific documentation.
