Stay away from a boost bottle on a drag motor, I would stongly recommend an override, and if i were you i would just build an awesome triple port 350 motor, there are guys that have been getting 95hp. out of that setup now. If i were you i would work with a builder, they will help you build a badass motor with everything setup how it should be.
