New user help advise, 440 duster

Hi I am looking at a duster with a 440 in it. My question is will this engine twist the frame of this car? I have done some research and I have read that the frame needs to be welded or reinforced so that the torque of the engine does not twist the frame. Will someone that knows take a look at this and tell me if this will hold up to the power of the 440? You might have to click view discription to see the underside pics. Thank.
