Bill is correct. A hemi is a shortened term of Hemispherisical combustion chamber. The spark plugs are positiond in the middle of the combustion chamber. The combustion chamber is half of a sphere (Hemisphere).
It has some drawbacks though. The heads are very large.
If you look at an old 426 Hemi and the Hemi of today, they are not the same design.
