To find #1, you need to:
1. Identify your engine's firing order: This is crucial. The firing order for a small-block Chevy 350 can vary slightly depending on the year and specific engine configuration (though common ones are 1-8-4-3-6-5-7-2). Consult your owner's manual or a reliable source like a repair manual specific to your vehicle year and engine.
2. Locate the #1 spark plug wire: Once you know the firing order, trace the #1 spark plug wire from the spark plug to the distributor cap. The terminal it connects to on the cap will be the #1 terminal.
In short: You can't just assume where #1 is. You *must* determine the firing order for your specific engine first.
