thanks bud, ive looked at those and they seem like a good deal for what you get. also, ive heard that 400's dont like to rev past 6000 and ive even read that you should never rev them past 6000. for some reason i just dont believe that. maybe its true but i just dont think it makes any sense. i would like to get as much rpm out of it as i can to get the most out of the cam. anyone else have any suggestings?
