Where is number1 on distributor cap Chevy v8?

The number 1 cylinder location on a Chevy small-block V8 distributor cap varies slightly depending on the year and specific engine configuration. However, it's generally found on the passenger side (right side) of the engine, and the firing order dictates its position on the cap itself.

To find #1:

1. Consult your engine's firing order: This is crucial. Common firing orders for small-block Chevy V8s are 1-8-4-3-6-5-7-2, but there can be variations. Find the sticker on the engine or consult a repair manual specific to your vehicle's year and engine.

2. Locate the number 1 spark plug wire: Once you know the firing order, trace the spark plug wire connected to cylinder #1. The wire will run from the distributor cap to the #1 spark plug.

3. Identify #1 on the cap: The distributor cap will be marked with numbers. The number on the cap where the #1 spark plug wire is connected will be the #1 position.

In short: You need your engine's firing order to definitively locate #1 on the distributor cap. Don't rely solely on assuming a position, as variations do exist.
