it will have plenty of power if you build it right... my truck has plenty to break the back tires loose in 5th!! building a 24v 500hp is goin to take sum parts to get too on a 12v you can be at 800hp with the same types of mods! trust me 500hp is plenty of power to drive every day, in my opinion sometimes it too much!! the 12v wouldnt be very driveable at all!! what do you plan oon using the truck for??? daily driver/ drag racing/ sled pulling/towing/etc?? that should help you decide what to put on the trucks as far as parts go!
