* Small Block V8 (e.g., 318, 360): These typically use a distributor with a mechanical advance. Timing is set using a timing light and is usually specified in degrees Before Top Dead Center (BTDC) at a certain RPM (often idle). The specific timing will be found in your owner's manual or a repair manual specific to your engine. Incorrect timing can severely damage these engines.
* Inline 6 (e.g., 225, 360): These also use a distributor and the timing is set similarly to the V8s, but the specifications will differ. Again, a repair manual is crucial.
* Cummins Diesel: Diesel engines have their own timing requirements, often involving injection pump timing which is significantly more complex than gasoline engine timing. Working on diesel timing often requires specialized tools and knowledge.
To get the correct timing information, you NEED to provide the following:
* Engine size and type: (e.g., 318 V8, 225 inline 6, 6BT Cummins)
* Your owner's manual: This is your best source for the factory recommended timing.
* A repair manual: (Haynes, Chilton, or a factory service manual) These manuals will provide detailed instructions and specifications for setting the timing correctly.
Without this information, any timing instructions given would be potentially damaging to your engine. Improperly setting the timing can lead to poor performance, engine damage, or even engine failure.
