To use a carburetor, you would need a complete engine swap with a carbureted 460, or a significant and extremely complex conversion involving:
* Replacing the entire intake manifold: The EFI intake is designed for fuel injectors and sensors. You'd need a carbureted intake manifold.
* Replacing the fuel system: This includes the fuel pump, fuel lines, and possibly the fuel tank if it's not designed for gravity feed.
* Replacing the ignition system: While you might be able to adapt some components, the EFI system's timing control is integral to its operation, and significant changes would be needed.
* Addressing emissions: Modern emission regulations make such a conversion very difficult and likely illegal in many jurisdictions.
* Custom fabrication: You'd likely need to fabricate numerous components to make everything fit and work correctly.
The complexity, cost, and difficulty involved make such a conversion impractical for most people. It's far easier and cheaper to simply find a carbureted 460 if that's your desired setup.
