+1 to that. If you bought that Big Red to modify then you will be pretty disappointed. About the only mods you could do to it would be a larger exhaust, 200x cam, and change the gearing (which even then wont give you many choices). With the mods you are trying to do, it sounds like you would be happier with an ATC200, 200s, or 200x. Look into one of these, they sound more like what you want.
