Interesting to note that they changed displacement to accomodate using the 6.1 rod and piston as well as adding the variable exhaust timing.

This quote rocks:
"Intake valve control was not chosen because its prime benefit would be improved low-end torque, something the 8.4-L V10 has plenty of, although the 560-lb·ft (760-N·m) peak is at 5000 rpm. Intake control would simply "translate to more tire smoke on a Viper," explained Chrysler SRT engineer Kraig Courtney."
