Building 383 Help

Hey all, I got my 383 back from the shop yesterday and I'm excited to rebuild it. Its my first engine so I'm going to need a little help assembling it and what to put in it in the first place. Its going in a 69 barracuda fastback, bored .030 over, everything else is standard and I'd like to keep the block as original as possible. Transmission is a 4 speed manual, ill probably leave it as that. Rear end is 8 3/4ths 4:10. I'm looking for at least 500 HP or so with something that doesn't destroy the block because its date correct for the car. I prefer low end (quick acceleration) over high end. I don't really have a set budget but I'd rather do it right now then have to redo later. I have everything stock for the engine, so if any of that can be reused, but I'd rather have performance. I've read about builds and have seen common suggestions for the mp 509 cam, aluminum heads, and a 440 crank instead of the standard 383 one. You'll have to bear with me on the limited knowledge. Thanks for all the help.
