suspension question

I have a 94 mustang that I am putting my 521 in and I am wondering what I should do to help hook up all the power. right now the car has strange adjustable struts up front with moroso drag springs and the rear has upr non adjustable control arms with strange adjustable shocks and moroso drag springs in back. the car also has frame connectors on it.

the car hooked hard with the small block in it, but not sure how it will hook with the big block. I am thinking of changing the k member to help remove some weight up front.

ok the question is do you think this will work on the big block? I am guessing 650-675 hp and the car will have a c-6 trans with a 3800 convertor for now on a 28x10 slick.

sure I am missing some info here but all help is appreciated.

It is really hard to mess up with that power level. I think that I would put an anti-roll bar in your current setup and see what it does.

thanks guys for the advise, this is really the first chance I have had looking at this. just wondering when you say replace the springs with stock do you mean all around? and I just got some double adjustable uppers and am looking into getting the anti roll bar soon as this is something I wanted to do anyway.
