there will be a casting there also. I have been thinking about who told me all this. It was an old man that has had a machine shop for ever and a day. just like there are better metal in cranks there were better metal in some blocks. He told me about this about ten years ago when I tool a block into him to get it machined. I wrote this stuff down somewhere but I thing it is at my office. If I cant find it i will give him a call monday and get the info from him again.
