is the o/p set on that roots blower.. would a procharger be better?
I'd forget the hp # and build for a nice fat torque curve..
mag hp# are nice but at the end of the day you have to ask, while looking at the dyno sheet, just how much of the time will I spin the engine past 4000-4500 ?
remember these trucks are not lite.. torque is king baby..
with the right parts you should get 450+ ft lb at a nice low rpm with that blower set up right.. meaning set up for the rpm you plan on driving at..
