Justin;
I did make a slight Boo-Boo on that first calculation which I went back & corrected. That approximately 4.7 oz would be correct if you were removing the .010" per side. We were actually speaking of removing .010" on the diameter so it needs to be divided by 2 thus 2.35oz for a .010" bore enlargement from a nominal .730" bore. The approximation itself is not within the "Formula" but I simply had to guess where the point would be in relation to the forcing cone to determine the length of bore over which metal would be removed. The longer the cone of course the less will be the length of the bore you are going to enlarge.
