Castings can be much more problematic because of lack of fill, cavities, and porosity. Also- machining the block allows for use of a much wider variety of aluminum. Not all aluminum makes good castings.

The benefits of a CAD/CAM program. Wouldn't wanna be the guy to program it manually.haha...

first off casting is not easier, I work in a machine shop in a foundry been through both methods. Second castings have a much higher probability of internal defects, and third tools to produce castings are very expensive especially the complicated shapes involved in a crank case or engine block, and finally once you've proved out your machining programs it's very simple to setup another block and let the machine eat unnattended nothing like run time

why do they have to ...machine the entire engine ?...even though casting of the engine block is mostly followed in most places.. casting is much more easier and less time consuming and it saves cost too..!!!

This is the art.

i seen on "How its made" they make molds out of sand and poor molten steel in it but i like this video!!

watching these machines, i get the idea of how amazing engineering is. A dedecation to mathematical precission in combination with design and arts.isnt this true creating? Wether the artist nor the worker has his mind in those two realms, only the engineer has.

Skyline gtr is a great example

some race engines are. Like I'm sure the F1 blocks must be made like this, But 99% of cars (including Ferraris) have cast iron or aluminum blocks
