406sbc horsepower guess

I am currently building a 400 small block chevy. It will be .030 over 10.2-1 cr with a .040 quench, 5.7 rods with kb hyper. pistons. Bowtie phase 2 heads mildly ported with 2.05 intake 1.6 exhaust valves. The cam will be a melling with 234/244 @.050 with .488/.509 lift. It will be fed by a hollley 750dp I havn't got an intake yet i'm open to suggestions. Could someone please desktop dyno this and give me some suggestions.

my (conservative) guess is ~450 horse/460-475 lb ft. Your peak HP will be around 52-5500 and your peak torque will be found around 4000, and pretty flat. This assumes a nice DP, like an RPM or a stealth.
