Need some advice on choosing an engine

Talk about great feedback... Thanks to everyone!
I definitely have some decisions to make. One thing I have decided, is I will most likely be buying a crate motor instead of building it myself, primarily because of cost and my lack of experience with building MOPAR engines. If it was a SBC or LS, I'd likely build it myself, but not if I go the stroked 400 or similar route. I'd like to end up with somewhere between 600 and 700 horsepower at the rear wheels. Assuming I can keep the cars weight under 3000 lbs, that should get me well into the 10's which is fast enough for me. I have heard about the intense care and feeding a 9 second street car requires, and I'm not ready for that.

Thanks again to everyone for the great advice and sharing your wisdom with a guy just getting back into MOPARs.

600-700 horsepower to the rear wheels? That is a fairly stout normally aspirated engine. Here is our single Dominator 500"/440 at 696 HP.
