To set the timing on a 1996 Ford Econoline 150 with a 300 six-cylinder engine, first, ensure the engine is at top dead center (TDC) on the compression stroke for cylinder number one. Then, locate the timing mark on the harmonic balancer and align it with the timing tab on the engine; the correct timing specification for this engine is usually around 10 degrees BTDC (before top dead center).
