It was very fascinating to watch and it makes me wonder if the origional casting molds for that block are still around and can be redeployed. With the cylinder head advancements now available, building a 600+ CI engine is far more practical now than when this block was cast.

Speaking of practicality, unless you're stupid rich and can afford not to be practical, this was nothing more than a "yes, it can be done" process. Now that I know in theory and with enough money, I can have my 557 block "thickened/reinforced" at a cost much much higher than a new aftermarket block...
