Over bore: How far is too much ?

Every block is different. I have a 73 360 block that's safe going .060 over. My machinist even said he'd take it .080 over for a stock street engine. On another note he said he just had a 360 block go through that had bad core shift and one side was fine for .060 and the other side was only good for .020 over. You never know where they are so if your building a high hp engine, especially a stroker have it sonic tested.
