1998 360 from a ram Help

Hi fellas, what I have is a 1998 360 from a ram, with fuel injection. Now what I want out of this motor is a nice street and strip runner, it will end up with a tunnel ram with 2-500 CFM hollys cause that set up just looks so damn cool. What could you fellas suggest for a build as far as pistons and cam. I would like to start off with a .040 bore, but the stock pistons are concaved and I guess it is a 9:1 compression, do I need concaved pistons? I am planning on keeping the stock heads with a 2.02 set of valves installed. This motor will start off in a 72 Dart but will end up in a 1952 Pontiac Chieftan that is going Mopar as far as drive train ( it belongs to my son). so what kind of advice am I going to get from the great minds here.
Thanks Ed
