What year 360?

I need a bunch of advise. I want to build a 360 for my 67 Barracuda vert. I will have to buy a 360 and I would like to know what year is best,if any, or does it matter? I would like to end up at 500+/- hp. Do I have to build a stroker or is there another way? I have alot to do besides the motor but I would like to find the best motor to use.
I have never built a performance engine and I haven't a clue as to what I will need to do. I have read discussions about .030-.040 over, cams, heads and so on. But what is the best thing to do?????
