Diagram of firing order for Chevy 350?

There isn't one single diagram for a Chevy 350 firing order because the order depends on the distributor's cap and rotor orientation. However, the firing order itself is always 1-8-4-3-6-5-7-2.

To visualize this, imagine the engine's cylinders arranged in a circle. You'd need to know the distributor cap's terminal arrangement to map the order onto the cap's terminals. Several resources online show images of Chevy 350 distributor caps with the firing order marked on the terminals. Search for "Chevy 350 distributor cap firing order diagram" to find these.

Remember that the firing order is consistent, but its placement on the distributor cap can vary slightly due to manufacturing differences.
