Which engine is Cooler?

I always thought the Viper V10 should have been a Hemi!
They could have developed it for the V10 Viper then spun off v8 & v6 versions for the truck and car engines. Still don't understand why it isn't a Hemi or have much of anything else in common with the other Mopar engines.

Now a mid engine Hemi would be cool in your truck.
