What makes a Hemi a Hemi?
 
Out of curiosity, how many Hemi owners know why their engine in a "Hemi" and what are the origins of the Hemi?

Are you asking why, or are you quizzing everyone?

If quizzing, yes, I do know. If you are asking: http://en.wikipedia.org/wiki/Hemi

More of a quiz I guess. I was doing some internet research about my 4.7 and came across some neat stuff about the Hemi and it got me wondering how many Hemi owners knew some of this info.

I read that link you posted plus this one:
http://en.wikipedia.org/wiki/Chrysler_Hemi_engine

True, they are not per the definition 40 years ago, but times change and so must the Hemi be redefined.... they are now "partially-spherical". Still a "Hemi", just not the same one. See here: http://www.autotropolis.com/wiki/ind...e=HEMI_Engines

practically the new ones are not true Hemispherical engines, but, technically they are

In a hemi engine, the top of the combustion chamber is hemispherical. An engine like this is said to have "hemispherical heads." The spark plug is normally located at the top of the combustion chamber in a hemi, and the valves usually open on opposite sides of the combustion chamber

did you know that Ford made a HEMI ?? it was called the Ford SHOTGUN engine, Ford stopped making them, because NasCar's president said that only small blocks were going to be used on the tracks

The BOSS 429 story is closely interwoven with NASCAR racing. In the middle to late 1960's Chrysler was dominating NASCAR racing with their radical new 426ci hemi powered racers. Ford needed a new weapon in this battle, and decided to take it to Chrysler by building a big block hemi engine of its own. Thus the Boss 429 motor was developed, and it was designed and built from the bottom up as an all out racing engine. However to use the engine on the NASCAR track, Ford had to first homologate a minimum number of engines into regular production cars, and the Boss Mustang was chosen for this. The new hemi motor was christened the Blue Crescent, but as the intake and exhaust ports in the huge alloy heads were so large, it was nick-named the "Shotgun".



You can buy a SHOTGUN HEMI brand new right now, from John Kaase, Cu. in. 429, 460, 520 & bigger

I don't know and don't lose any sleep either

It's called a hemi because of the hemisphereical shape of the combustion chambers in the heads, vs. the wedge shape of most other motors...... Originally the spark plug location was centered between the two valves in the combustion chamber..If i remeber correctly, Chryslers first Hemi was a 392 Cu In, around 1956 perhaps

Very interesting stuff the HEMI history. I was also amazed reading Yankees history lesson right now remembering how most if not all of the auto makers made their mark on the race track in the old days. Unfortunately today as society has become more educated or evolved (supposedly, because I don't see it) NASCAR is associated with Rednecks, Booze, and Guns. How things have changed (not always for the better).
