Wanting 500 hp (or close) out of a stock stroke 360

My old 340 ran 7.24 at 96 mph on pump 93 at 3240# in my 69 Dart. 425-450 hp??

.030" over with Ross flat tops, Curtis Boggs ported edelbrocks, 11.4-1, a Hughes hydraulic 237/242 at .050", .584/.592 with Hughes 1.6 rockers, Deep port matched Weiand X-Celerator intake and a Quick Fuel Q-750, 4.30 gears and a 727. I tried shifting from 6000 to 6800, it ran the quickest 64-6600. So I shifted it at 6400.
