Hmm so you just going to throw money at it without even measuring.. makes sense that you would do that. As it's pretty clear already that you have no idea as to why machine work can't and won't fix core shift. Then you try and bandage it up by throwing more money at a junk block. The friend I had probably would have scrapped your high dollar junk in the salvage yard. So go study core shift. And why it can't be fixed. And all of the areas that it effects and also why after spinning a main that the block is now crooked. Don't be cheap and lazy little buddy. Have faith you will get there. Just takes time
