banshee409

I have had dirtbikes and currently have a 400ex, i want a banshee, im going to be doing hill climing and some jumping and wheelies/playing around on. Would a stock one be ok for this, i want something with tons of power for some fun. I know a guy that can get me dortbikes and quads dirt cheap so i can use the rest of the money in the motor.What all comes in the kit?

I am going to be buying a banshee in about a month, and i was thinking about putting a 409 in it, im new to banshees so what will all have to be done and how much would the kit cost around? Thanks .
