  The colloquial application of the word "Hemi" comes from the hemispherical combustion chamber of engines built for the Chrysler Corporation between the late 1950s and today. Perhaps the most famous of these engines were the large-displacement powerplants developed for various racing teams in the '60s and '70s. After the Arab oil embargoes constrained fuel supplies mid-decade, these engines largely disappeared. However, in the early 2000s the Hemi began to make a comeback, and today it is available in a wide range of power and torque options. Among the most notable are those built by Arrington Engines, which makes stock engines more powerful.

• The Arrington 5.7-Liter Hemi is expanded to produce a monster engine in a small package up to 392 horsepower. The engine's footprint is perfect for a range of Mopar body/chassis configurations, including light trucks with no need for internal frame modifications.
  
  

426 Hemi

• For medium-duty trucks, the Arrington 426 Hemi produces up to 585 horsepower, with an outstanding combination of performance and tractability. The company beefs up the torque to 560 ft.-lbs., a 30 percent increase over the stock Hemi.
