was the shape of the combustion chambers of some of the most powerful and successful Chrysler
engines in the '70s, the most notable one being the 426. The shape was in use long before Chrysler
came up with it; the earliest HEMIs
can be found
in engines built in the '20s.
Now, the HEMI
is proof that brand name affinity sells cars, and that nothing in the automotive industry is sacred. The current design
is a ripoff of a Porsche design
. If you want to visualise
what the current HEMI head
looks like, take a pear, cut it in half lengthwise, and lie it down. The big circular section is where the intake valve
is, and the small
one is where the exhaust valve
is. The TWO spark plugs
reside at the "waist" of this pear-shape, one on each side. Note that there isn't two plugs
performance, but rather because one plug off to the side couldn't hope to burn all of that fuel.
I park my Dodge Ram with the HEMI
right next to my new Olds 4-4-2 minivan and Ford Escort
Damn, I wish someone
told me that this HEMI
crate engine weighed 5000lb and is only
suitable for drag racing.
