turbo small block help

[70TWO NOVA]

ok, well a couple of friends and i are contemlating building a small block for a Nova that a friend owns. We want to do something different so we decided to go with a single turbo for a power adder. i would like to get some feedback from you guys on what you think would be a good size turbo for what we plan on building and some info on turbo cams if possible ( what is different in terms of lift, duration overlap/lobe centerline, etc for turbo motors). We are going to run a 355 with all forged internals, single plane intake,850 or so blow through carb, msd 6btm box w/ msd pro-billet distributor, aluminum heads by Jegs w/ 2.05 I/ 1.60 E valves, 197cc intake runners and 72cc chambers (8.5:1 CR). any feedback or help will be greatly appreciated. We want to do around 600-700 flexplate hp anh tq and not exeed 8-10lbs of boost. we are also going to be running a th-400 w/ a 3500 stall converter.
