      A Hemi indicates the top of the combustion chamber has a Hemispherical shape, rather than the typical frying pan type shape.

      The increased size of the chamber means additional fuel and air can be introduced, which increases power output.

      It’s old tech like carburetors. It’s wasteful on fuel, but MOPAR fans love it.

        Doesn’t it also mean a higher compression ratio? Meaning more power behind the same A:F ratio? Or am I as dumb as the guy who put the stickers on that truck?

      It’s something rednecks will ask other rednecks about whether they have one or not. If you see that sticker, there is about a 30 percent chance that the driver of the vehicle is drunk.

      It’s a type of engine design found mainly in certain pickup trucks. I don’t know why but it’s an important thing to some people.
