Metal forming process in which molten metal is forced into a cavity or mold under high pressure.

is a metal casting process that is characterized by forcing molten metal under high pressure into a mould cavity.

Die casting is a process in which molten metal is forced under high pressure into mold cavities. The metal hardens to get a desired shape. In recent times, plastic molded parts have replaced die-casting, as they are cheaper and lighter than die cast parts. Die-casting can be done using a cold chamber or hot chamber process.

Custom Die Casting is when you do a "Make-Over" to a die-cast toy. For example: I have a Hot Wheels Car and I decide to color it all red with a Sharpie. It is now a Custom Die Cast

The combustion chamber size of the heads with the casting number 376450 is 60cc. It is possible to install larger valves.
