supercharged "HEMI" six cylinder

Are you aware that Chrysler (or whatever their current name is this year) has a copyright on "hemi". They can use that word anyway they like.
I don't recall which came first, but back in the (I think) late '40's there was an overhead valve conversion for the Ford flathead V-8. It was called the "Ardun" conversion, and was a Hemi head. The designer was Zora Arkus Duntov of Chevy/corvette fame. If you look at the Ardun valve train, it is almost identical to the Chrysler Hemi valve train.
