To set the timing on a 1990 454 SS Chevy, first ensure the engine is at operating temperature. Then, locate the timing mark on the harmonic balancer and the timing tab. Use a timing light to check the ignition timing while the engine is running; adjust it by loosening the distributor hold-down bolt and rotating the distributor until the desired timing mark aligns with the tab. Finally, tighten the hold-down bolt and recheck the timing to ensure it remains at the correct setting.
