1976 360 engine swap
Please understand I have seen the drawings, but never done it myself..so i'm just tossing this out there too. But, that being said, even measuring out from the center...he's going further out if it's removed from the outer edge. (I dont know if it is, but my 360 flywheel has a 1/2 moon out of one edge) The amount of material to remove depends on the distance from center, and if you remove it from a larger diameter edge, you should be removing less material. Because the same volume removed from a longer distance away from center will carry more mass offcenter when rotated. God I hope that makes sense...
