Timing chain and gear in 318 dodge correct setting on timing distributor 83 truck v8?

There's no single "correct setting" for the distributor on a 1983 Dodge 318 V8 without further information. The distributor's position is determined by the engine's timing, and that timing is specified by the manufacturer. Here's what you need to do:

1. Find the Timing Specifications: Consult your 1983 Dodge 318 V8 engine's repair manual or a reliable online resource specific to that year and engine. The timing specifications will be listed there, often expressed as degrees Before Top Dead Center (BTDC) at a specific engine RPM (like 5-10 degrees BTDC at idle, and maybe a different value at higher RPM).

2. Verify Timing Chain/Gear Alignment: Before adjusting the distributor, ensure the timing chain or gear (depending on your specific engine configuration; some use a chain, others a gear) is correctly aligned. Your repair manual will have instructions and markings for proper alignment. Incorrect timing chain/gear alignment will render any distributor adjustment useless and potentially harm the engine.

3. Set the Timing: This requires a timing light.

* Install the Timing Light: Connect the timing light according to its instructions. This involves clamping the light's sensor to a spark plug wire.

* Locate the Timing Marks: Find the timing marks on the engine's crankshaft pulley (or damper) and the timing pointer on the engine block.

* Set the Engine to the Specified RPM: Start the engine and increase its RPM to the specified setting in your engine's timing specifications (often idle RPM).

* Adjust the Distributor: With the engine running at the correct RPM, use the timing light to observe the crankshaft pulley markings. Rotate the distributor slightly (usually with a wrench or socket) until the timing mark aligns with the timing pointer at the specified degrees BTDC.

* Tighten the Distributor: Once the timing is correct, securely tighten the distributor hold-down clamp.

Important Considerations:

* Vacuum Advance: Many distributors have a vacuum advance mechanism. Make sure this is connected and functioning correctly. Improper vacuum advance can significantly affect timing.

* Mechanical Advance: Similarly, the distributor has mechanical advance weights that modify the timing as the engine RPM increases. Ensure this system isn't faulty.

* Professional Help: If you're uncomfortable with this procedure, it's best to take your vehicle to a qualified mechanic. Incorrect timing can cause engine damage.

Without the specific timing specifications for your 1983 Dodge 318 V8 engine, any further instruction would be potentially inaccurate and could harm your engine. Find the factory specifications first, then follow the steps outlined above.
