Instead of a "kit," you'll need to source the following components individually, and likely engage a professional mechanic specializing in alternative fuel conversions:
* Propane tank and regulator: These need to be sized appropriately for the engine's fuel requirements.
* Propane mixer or carburetor: This is a crucial component; you'll likely need a custom-built or modified system to properly mix propane and air for combustion in the 460. This is a complex aspect of the conversion.
* Fuel lines and fittings: Specialized lines capable of handling propane are required.
* Ignition system adjustments: Propane requires different ignition timing and possibly different spark plugs for optimal combustion.
* Vaporizer (possibly): Depending on the propane system used, a vaporizer may be needed to convert liquid propane to a gaseous state for combustion.
Where to find the parts:
* Propane tank and regulator: Welding supply stores, RV supply stores, or propane distributors.
* Other components: Finding a propane mixer/carburetor and other specialized parts might involve contacting automotive shops specializing in alternative fuel systems or searching online marketplaces (like eBay) for used or custom-built components. This will likely involve a significant amount of research and possibly custom fabrication.
Important Considerations:
* Legality: Check your local and state regulations regarding propane vehicle conversions. You'll likely need inspections and approvals.
* Safety: Propane is a flammable gas; proper installation and safety precautions are absolutely essential. Improperly converted vehicles can be incredibly dangerous.
* Cost: A complete conversion will be expensive, potentially costing more than the engine is worth.
* Expertise: This is not a DIY project for most people. You absolutely need a qualified mechanic experienced in alternative fuel conversions to handle this.
In summary, there's no "kit." The process involves custom engineering and is best handled by professionals with the necessary expertise and equipment. Contacting specialized automotive shops or alternative fuel specialists is your best starting point.
