Check out half the cars in Australia nearly, ha ha.. they run dual fuel all over there. One of the cars I imported was dual fuel ever (I took off all the propane stuff)
You just have to have the mixer and what not mounted along with the carb, flip of a switch to activate the propane solenoids and what, and you are set.
Be sure and hard hardended exhaust seats though when running on propane. You'll love how clean it keeps the engine too though
