Drive Train Upgrade Suggestions

All i can say is Welcome to Fabo. :)

Just too many choices/directions this could go for me to comment right now.

My main advice would be to take your time and look/research other Cuda's you like and make a plan from there. Spring is right around the corner, so maybe attend some Mopar get togethers in your area if available and talk to some people. Might give you a idea of where you want to go with the car. Good luck, and again, welcome to the best site on the net.
