10. 5.7-Liter Hemi V8
For over 30 years, Chrysler didn’t produce a Hemi engine or anything like the original concept. The company produced a lot of interesting, powerful engines, but nothing with hemispherical combustion chambers. Although the Hemi was absent from the market after 1971, its popularity was bigger than ever. That was especially due to classic muscle cars becoming popular and highly sought-after collectibles.
That is why Chrysler decided to revive the Hemi engine, although in modern form with modern construction techniques and materials. In 2003, they installed the first modern Hemis in the Dodge Ram. It featured 5.7-liter displacement and 345 HP.
The basic construction with two valves per cylinder and the push-rod design stayed true to the original concept from 1951. You can find the modern 5.7 Hemi in numerous Chrysler, Dodge and Jeep models up until 2009 when it received its first makeover.
