Where is number one on the distributor cap of a 1962 Chevy 409?
The numbering on a distributor cap is dependent on the firing order of the engine, not the year or make of the vehicle. The firing order for a 1962 Chevy 409 is 1-8-4-3-6-5-7-2. Therefore, the number one spark plug wire would be connected to the terminal on the distributor cap that is adjacent to the terminal that the number eight spark plug wire is connected to.
