How do set timing on a 1994 c1500 pickup with a 5.0 motor?

To set the timing on a 1994 Chevy C1500 pickup with a 5.0L motor, first, ensure the engine is at operating temperature and then turn off all electrical accessories. Locate the timing mark on the harmonic balancer and the timing tab on the engine. Use a timing light to check the timing while the engine is running; adjust the distributor until the timing mark aligns with the specified timing degree (usually around 0 degrees for this engine). Finally, tighten the distributor hold-down bolt and recheck the timing to ensure it remains correct.
