From what I have been told, the cranks are good to 600hp and the rods should do the same if you have them shot peened and resized. I hear the pistons are the weak point of the rotating assy.

You may want to look into upgrading the rear end in your SS. Those 7.5's break behind stock 305 power, especially if you ever intend on making that kind of power and taking it to the track.

The stock crank and rods have been to over 1000hp before, The generic numbers out there is 600-700hp but many have made more power then that. In this game its all a game of chance, and how much you want to gamble and how many times.
