Plymouth Hemi Engine original vintage advertisement. Ask our
engineers what makes a hemi-powered anything the one to beat
and they'll probably give you a lot of talk about volumetric
efficiency, heat dissipation, flame travel, gas flow and that
sort of technical stuff. Don't believe it. You can't make an
engine like the Hemi with figures and formulas alone. It's gotta
be voodoo baby! Beat it.
