5.9 Magnum-833od Q

Check the crank to see if there's even any reason it won't fit as-is. It's not a given that the pocket isn't machined to depth if not a finish bore- lots of them are, and there's no reason to cut anything. If it's not full depth and the engine is already assembled, then it can be hand drilled since it's a non-critical dimension and you're using the roller bearing in the convertor pocket anyway.
Not a fan of cutting the input shaft, even though it gets done way too often.
