Could Edelbrock cast a flathead block

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.

To make a lost waxmold the size of a flathead block and get all out of it isn´t easy...
3D printing it in PLA and then heating it up enough to make it burn up is more likely to work.
Cores are made differently and chemicals are added to make it cure and be tuffer then the rest of the mold and you use steel wire to keep it in place.
How do you hang the cores in a lost waxmold ??
Its not as easy as it can look at first sight.
