Hemispherical means circular, the 4.7L cylinder head combustion chambers are
not completely circular or Hemi shaped but they are very close! And, the
valves are across from each other instead of beside each other like in the
318/360. Furthermore, the sparkplugs go in from the top of the head instead
of the bottom side. These are all characteristics of the original Chrysler
Hemi engines of the 50', 60's, and 70's. This is as close to a true Hemi
engine as you can get, without being one!

Subject: DML: New 4.7L V8 = new hemi engine???
The 4.7 is a semi-hemi head engine. the heads have a hemispherical
combustion chamber with one side being flat. this is why they are only a
semi-hemi and not a true hemi. the 318 has a conventional combustion
chamber. Does this make sense to you? I'm sure someone can better explain
if not...
