Where is the timing mark on a 93 5.7?

On a 1993 5.7L engine, the timing mark is typically located on the harmonic balancer or crankshaft pulley. It is usually a notch or a line that aligns with a timing indicator on the engine block. To set or check the timing, you would need to locate this mark and align it with the specified timing reference point, usually at TDC (Top Dead Center) for cylinder one. Always refer to the vehicle's service manual for exact specifications and procedures.
