I need a little help. I have always been a small block guy and dont know all that much about Hemi motors. This past weekend I went home to deer hunt and was driving around my uncle's pasture when I discovered this motor. It is an old irrigation motor and was run on propane. It is complete, including a starter. My uncle says it ran great in 1971 when he quit using it. He gave it to me and is going to load it in my pickup with the skid loader the next time I get back home. He couldnt remember when he bought it, but bought it new. He also remembered changing the oil every week. I am assuming I can convert it to gas with a rebuild and it will work fine as a car motor? It is not locked up and I am really excited about it. Should I be? Or am I in for a disappointment? Thanks for any advice on it.
