Found a guy trying to sell his 2006 zx6r with a blown motor for very cheap, $3500 to be exact. He's also adding a motor with only 4900 miles and he claims he has everything for it. Providing that he does, I was wondering how hard/long it is to do an engine swap? I have mechanical experience as does my father and brother in law so I'm not worried about messing it up. Just wondering how much time it would take and if it's worth it? Thanks!
