Parts of cylinder block

A bare cylinder block does not contain any other parts. Assuming it is an internal combustion crankshaft/camshaft style engine it should have the following:

• cylinders
• crankshaft journals
• camshaft journals
• mating surfaces for necessary components such as cylinder heads, oil pan, exhaust and intake manifolds, and etc.
• drilled/tapped holes for the necessary fasteners (bolts/studs)
• other holes/passages as needed

Note: Cylinder heads usually contain the exhaust and intake manifold mating surfaces.
