How engine block is manufactured?
Manufacturing of engine blocks are mainly done using sand casting, although die casting also used it is more cost effective as the die wear out easily due to the high temperature of the molten metal. The casted engine block is then machined to get the surface finish and coolant passages.
Is Cast Iron Block vs aluminum?
Because iron is more rigid than aluminum, it won’t deflect and distort as much under high cylinder pressures. Modern aluminum blocks are pretty strong, but a properly built iron block is still ultimately going to be stronger, and that strength offers some benefits that might be less obvious.
