Hi, new guy here. I just purchased a dyna glide sport that was dumped. I bought it for a project. My question is this: it has a 124 S&S engine which has the original engine # stamped on it. The frame and title vin #'s match so that is right but I was surprised that the same # is on engine, or at least an abbreviated portion of it. Is this a normal thing for S&S engines? Thanks
