Question

Quizplus · Accepted Answer

Both statements are correct. Engine blocks can indeed be made from either cast iron or aluminum, depending on the application and desired characteristics. Cores are used in the casting process to create internal cavities within the engine block, such as water jackets for cooling and cylinder bores where the pistons move.
