However, a good starting point is generally between 0.035" and 0.045". This range is commonly recommended for many 305 engines of that era.
To find the optimal gap for YOUR specific engine:
1. Consult your owner's manual: This is the best source of information. If you don't have the original manual, you might find a downloadable version online.
2. Check the spark plug box: The packaging of the spark plugs you're using should specify a recommended gap range.
3. Refer to a reputable repair manual: A Haynes or Chilton manual for your year and model Camaro will provide the recommended spark plug gap.
Important Considerations:
* Ignition system: Different ignition systems (points, electronic ignition) may require slightly different gaps. An electronic ignition system often prefers a slightly smaller gap.
* Altitude: Higher altitudes generally require a slightly larger gap.
* Fuel type: The type of fuel you use might influence the optimal gap.
* Plug type: The type of spark plug (e.g., AC Delco, Champion, etc.) will have a recommended gap.
In short: While 0.035"-0.045" is a reasonable starting point, always prioritize the recommendations from your owner's manual, the spark plug packaging, or a reliable repair manual specific to your 1970 Camaro 305. Using a gap significantly outside of the recommended range can lead to poor performance, misfires, or engine damage. Use a spark plug gapping tool for accurate measurement.
