Yes, the engines are very special, in pretty much every conceivable way (unless you prefer burning rice). Maybe some of you don’t remember the begning, most people were shocked to hear Dodge offered a 5 year power train warranty on a new (unproven) SC 707hp car! Everyone was shaking their heads thinking that Dodge was going to find a lot of easy loopholes to not honor that warranty. Fast forward… Those same first run cars are running strong and selling for sky high prices!
“Hemi” is short for hemispherical, half a sphere. I have never seen the head of a 426 but from what I understand it was close to or an actual hemisphere. And it had pleanty of room for a second spark plug. Dodge marketing wanted to capatilize on the Hemi legend and came up with the modern “hemi”, which is not a hemisphere. I have not actually seen the head of a 6.2, but it is my understanding it is a partial sphere, I guess close enough for the Dodge Marketing Department, and not a bad marketing idea, unless you are a hard core mechanical guy (like me) in which case it makes me cringe, but not so much not to enjoy it!
