HEMI Nation
HEMI is the short name given to engines built with a Hemispherical Combustion Chamber. The HEMI was invented by Chrysler in 1951. There have been 3 major designs.
All hemis have 8 valves but what makes them different is that each cylinder has two spark plugs. The increased cross air flow improves the efficiency of the engine.
HEMI engines have either 5.7, 6.1 or 6.4 liters (one customized Charger was built with a 7.0L engine). They deliver better gas mileage, increased torque and more horsepower than there non-hemispherical counterparts.
The HEMI isn't exclusive to trucks and sports cars. It is also available in Jeep models, and Chrysler 300s. We have a nice variety on the lot.
