* Year of manufacture: Different years of the 350 have different camshafts, which affect the optimal timing.
* Modifications: Any modifications to the engine, such as a different camshaft, intake manifold, or exhaust system, will change the ideal timing.
* Intended use: Performance builds require different timing than street-driven engines.
Here's a general guideline for stock 350 Chevy engines:
* Initial timing: Typically around 6-10 degrees BTDC (Before Top Dead Center)
* Total timing: Around 34-36 degrees BTDC
To find the specific timing for your engine, you can:
* Consult a repair manual for your specific year and model: These manuals provide detailed information about the recommended timing for your engine.
* Use a timing light: Connect a timing light to the number one spark plug wire and observe the timing marks on the harmonic balancer.
* Consult a professional mechanic: They can diagnose your engine and set the timing correctly.
Important Notes:
* Setting the timing incorrectly can damage your engine. It's essential to set the timing correctly and follow the manufacturer's recommendations.
* Always use high-quality spark plugs and wires. This ensures proper ignition and reduces the risk of misfires.
Remember that these are just general guidelines, and the best timing for your engine may vary. It's always best to consult a reputable source for specific instructions and guidance.
