What is the Correct timing for a 92 Chevy 350?

The correct ignition timing for a 92 Chevy 350 with a conventional distributor is 0 degrees before Top Dead Center (BTDC). This timing is typically set with a timing light, which is used to align the timing mark on the engine's harmonic balancer with a reference mark on the engine block or timing cover.

To set the timing, follow these steps:

1. Connect a timing light to the engine. The light should be connected to the "negative" terminal on the battery and to the "cylinder number 1" terminal on the distributor cap.

2. Start the engine and allow it to reach operating temperature.

3. Aim the timing light at the timing mark on the harmonic balancer. The timing mark is typically a notch or line on the balancer.

4. Adjust the distributor cap until the timing mark lines up with the reference mark on the engine block or timing cover.

5. Tighten the distributor cap.

6. Turn off the engine and disconnect the timing light.

Note that the ignition timing may need to be adjusted if you change the engine, camshaft, or ignition system. It is important to consult the service manual for your specific engine to determine the correct ignition timing.
