* Engine modifications: A stock engine will have different timing requirements than one with performance modifications (camshaft, intake, exhaust, etc.).
* Fuel type: The type of fuel (regular, premium, etc.) affects the ideal timing.
* Altitude: Higher altitudes require different timing.
* Ignition system condition: A worn distributor or ignition components will also impact the ideal timing.
Instead of a specific number, you need to consult your engine's specifications. This information might be found in:
* Your owner's manual: If you still have the original manual for your vehicle, it should specify the recommended base timing.
* A Ford shop manual: These manuals provide detailed specifications for various Ford engines, including the 460.
* A reputable online resource: Websites specializing in Ford vehicles or engine repair may offer timing specifications for different variations of the 460. However, always verify the information's source carefully.
Generally, the base timing for a stock 460 is somewhere between 8 and 12 degrees BTDC (Before Top Dead Center). However, this is just a starting point. You will likely need to fine-tune the timing using a timing light and a method for adjusting the distributor. Improper timing can cause poor performance, reduced fuel economy, and engine damage. It's best to have this done by a qualified mechanic if you're not experienced with engine timing adjustments.
Important Note: Simply finding a number online and setting your timing to that value without understanding the variables is risky. Incorrect ignition timing can severely damage your engine.
