The timing mark on a 3400 Chevy Venture engine is typically located on the harmonic balancer and aligns with a pointer on the engine block. For proper timing, you need to set the mark to the specified degree before or after top dead center (TDC), depending on the engine's requirements. Refer to the vehicle’s service manual for the exact timing specifications and procedures. Always ensure the engine is at the correct operating temperature when making adjustments.
