* Specific year of the engine: The Ford 300 was produced over many years with design changes.
* Specific bolt or nut: Head bolts, main bearing caps, connecting rod bolts, etc., all have different torque specifications.
* Whether the engine is being assembled or repaired: Assembly procedures might call for different torque specs and sequences than repair.
To find the correct torque specifications, you must consult a Ford shop manual specific to the year and model of your vehicle. These manuals will provide detailed torque specifications for every fastener on the engine. Using incorrect torque values can lead to engine damage.
You can often find these manuals online (though be wary of unofficial sources) or from automotive parts stores. Providing the year and model of the vehicle the 300 is in will allow you to find the appropriate manual.
