for your non-turbo application there, Id suggest a 5.0 block so you get the benefit of a roller cam (w/o the expense of a retro kit).
For your 550-600 HP app, that is beyond a stock-block IMO. Look at a Sportsman block or other aftermarket-type block, which is serious $$$. Otherwise you are looking at hi-grade internals, stud girdle, and lots of prayer.
