* Engine specifics: The exact model of the 350 (e.g., a small-block Chevy 350, but there were many variations in camshaft, compression ratio, and other internal components across the years). A high-performance engine will have different timing than a stock engine.
* Camshaft: The camshaft profile significantly influences the optimal timing. Different camshafts have different intake and exhaust valve opening and closing events.
* Ignition system: The type of ignition system (points, electronic) also affects the ideal timing.
* Engine modifications: Any modifications (headers, intake manifold, carburetor, etc.) will alter the ideal timing.
You cannot determine the correct timing without consulting the owner's manual specific to your exact engine and vehicle configuration. Even then, the manual will likely give a *range* of acceptable timing, and fine-tuning might be required based on your engine's performance.
To find the correct timing:
1. Locate your engine's identification number: This will help you pinpoint the exact engine specifications.
2. Consult a repair manual: A Haynes or Chilton manual specific to your 1980 Camaro with the identified 350 engine will provide the correct timing specifications.
3. Use a timing light: Once you have the timing specification, use a timing light to check and adjust the timing according to the manual's instructions.
Attempting to guess the timing can lead to engine damage. Always refer to the proper documentation.
