Both the Dodge 318 (5.2L) and 360 (5.9L) V8 engines use the same firing order and cylinder numbering system. They're numbered from the passenger side (right) front to the rear, then the driver's side (left) front to rear.
Specifically:
* Passenger Side: 1-3-5-7
* Driver's Side: 2-4-6-8
So, cylinder 1 is the front-most cylinder on the passenger side. Cylinder 2 is the front-most cylinder on the driver's side, and so on.
