And again IF you watch the process that Ferrari uses today to cast new (and old) engines, it would be very easy to do especially if a CAD drawing exist on a computer. NOW ,the cost to have such equipment OR the wide spread usage of such equipment may be a different story. AGAIN, Ferrari went from a CAD design to a 3D printing of the block (in some form of low heat plastic, then poured a harder higher heat tolerant molding wax in the 3D block for a negative of the block, Then melted out the 3D printed block, then did sand cast molds of the negative and cast the blocks. VERY simple and done primarily by computer and 3D printing (OR Negative 3D printing) and a 3D sand casting mold machine. Watch "How Its Made" supercar series. VERY slick operation. AN within this operation one would think that within the CAD program you could MAYBE make improvements to the original block with respect to thicknesses and such.
