2. Dodge Ram SRT-10 Viper V-10. How could I not put this on the list?
The equation is simple, just like the 454SS and Lightning: lightest fullsize truck + bigest engine possible = fun. Add the Viper's ginormous engine, make it look great with a mean hood and fascia, and give it a manual transmission. What's not to love? With 8.3L, the unmistakable sound of a V-10 (even though we all know a V-8 sounds perfect) and 500hp, the regular cab Ram SRT-10 was capable of low 13-secont 1/4 mile passes. How is this engine not #1?
I've gotta give credit to Harley Camilleri for the awesome photos of the Ram.
