Okay, if drag racing only and you're going to run race gas then 13:1 compression will work. It will help make power that is for sure. An electric water pump can be helpful on a drag race car since you can run the pump and the fans while you are in the pits to cool the engine down. It really just depends on how you want to build the car.
I recommend controlling timing with the Sniper for a street engine but on a race engine you could keep the MSD.
