* Cam Spec: The camshaft used significantly affects the optimal ignition timing. A stock cam will have a different ideal timing than a performance cam.
* Ignition System: The type of ignition system (points, electronic ignition) influences timing.
* Fuel: The type of fuel (regular, premium, etc.) will slightly alter the optimal timing.
* Altitude: Higher altitudes require slightly different timing.
* Engine Condition: Wear and tear on the engine can affect its performance and optimal timing.
For a stock 1976 Dodge 360 with a stock cam and ignition system: A good starting point is usually between 4-8 degrees BTDC (Before Top Dead Center) at idle.
However, this is just a starting point. You need to consult your owner's manual (if you have one) or a reliable service manual for your specific engine. These manuals provide the recommended initial timing setting and usually detail a procedure for fine-tuning the timing using a timing light.
Crucially, you should *not* rely solely on a generic answer. Incorrect timing can damage your engine. You should:
1. Consult a service manual: This is the most reliable source of information.
2. Use a timing light: Accurately set the timing using a timing light and the instructions in your service manual.
3. Fine-tune the timing: After setting the initial timing, you may need to fine-tune it for optimal performance and efficiency. This often involves adjusting the timing slightly while monitoring engine performance.
In short, find your vehicle's service manual. Don't guess – improper timing can seriously harm your engine.
