do you/have you ever owned a bike? you apparently own a 400hp. i had a 400hp ws6 and also own a newer 600 and the 600 would take the ws6 from a dig or roll IMO. i can feel the difference between the two. its not totally out of the question for either one to win, but i think maybe a slightly modded c5z06 would be something that could take it or a c6 z06. not sure.
