Here's what that means:
* Cylinder 1 fires first, then cylinder 8, then 4, and so on.
* This sequence ensures smooth and efficient engine operation.
Note: This firing order applies to most 350 engines in the 1970s, but it's always a good idea to double-check your specific engine's specifications for confirmation. You can find this information on the engine block itself, in the owner's manual, or by consulting a repair manual for your year and model.
