The cylinder numbering on a Chevy 454 (Big Block Chevy) is arranged in a passenger car configuration, meaning that the numbering sequence proceeds from the front of the engine to the rear, starting on the passenger side.
Therefore, the firing order affects the numbering, but the cylinders are numbered:
* 1-8: 1, 3, 5, 7 are on the passenger side; 2, 4, 6, 8 are on the driver's side. The sequence from front to back is 1, 2, 3, 4, 5, 6, 7, 8.
