To be certain, you should:
* Consult a repair manual specific to your 460 engine's year and application. This is the most reliable method. The manual will have diagrams showing the exact location.
* Look closely at the bottom of the oil pan. The plug is usually a hex-head bolt or a similar type of fastener. It's typically located towards the front or slightly offset to one side, but not directly in the center.
* Feel around the bottom of the oil pan carefully. The drain plug will be a recessed, somewhat protruding bolt.
Caution: Be extremely careful when locating and removing the drain plug. The oil will be hot if the engine has been running recently. Use appropriate safety measures, including gloves and eye protection. Have a suitable drain pan ready to catch the oil.
