500 hp is a lot of hp for the st. but if youve got it you should use it, and the only way you can do that it you have to have something that will stay togother and hook up when you wont it to. you could put the 500 hp motor and 7.5 dif. with 4.56 gear in it and ride around and porfile all you wont, but if youer (going to hammer it) as you say then you need the 9" dif. with at least frame ties installed. the ladder bars or 4 link would be for handling not strength. leaf springs should be strong enough but you cant do much with them far as handling goes. put your 500 hp motor in and the 9" dif. use your leaf springs and install some frame connectors youll need to look at the shocks. thats my story and im sticking to it.
