3. Dodge 8.3 and 8.4-Liter V10
Dodge presented the next generation of the Dodge monstrous engine along with the second generation Viper in 2003. The basic construction was the same, but they updated the cylinder heads, along with the cooling and valve train. The displacement grew to 8.3-liters or 505 CID, and the power climbed to 510 HP. This engine went to the Dodge Viper and also the Dodge Ram SRT-10 pickup, making it the fastest truck in the world.
In 2008, Dodge introduced a slightly improved version of the same engine which now produced 600 HP with a slightly bigger displacement at 8.4-liters. In 2013 with the introduction of the last generation Viper model, the 8.4-liter V10 returned but with 640 HP. Unfortunately, Dodge Viper production stopped in 2017, which meant Dodge also stopped producing this fabulous engine as well.
