How do you set the timing for a 1984 El Camino 305?

To set the timing for a 1984 El Camino with a 305 engine, first ensure the engine is at operating temperature and then turn off the ignition. Locate the timing marks on the harmonic balancer and the timing tab, ensuring the engine is at the correct timing position (usually 8-12 degrees BTDC for this model). Use a timing light to check the timing; if it's off, loosen the distributor hold-down bolt and adjust the distributor until the timing light shows the correct setting. Finally, tighten the bolt and recheck to confirm accuracy.
