What happened to the 302? If it's still there, there are ways to patch that crack that work a lot better than JB Weld. Even Marine Tex will do a better job, and there are also permanent repairs such as overlapping threaded plugs that will seal up a crack for good. I'd hate to think that a good 302 is rotting away in a piece of yard art!
