Precision through computer simulations, take 2jz for example, a huge and over-built in every corner of the block, but it’s extremely heavy and inefficient especially being a cast iron block.

Modern engines are smaller, lighter where mass are only necessary added based on the engine’s weak points. Materials selections have also improved for better costs to strength.
