Im getting ready to get rid of the old tired 305 in my truck for a 350. My friend knows a guy who has a 350 crate that is a few years old, but has never been in a truck or anything. It just sits in his garage. He was going to put it into a truck, but he sold the project, and said i could have this motor for $500. Is this a good deal, and is the swap a direct bolt in?
