(i'm assuming you have some serious money to spend on this -you didn't specify-)
You have exactly what i want my car to be! Get a forged crank (if you want it to spin upwards of 7k rpm, don't get a reground crank with larger bearings, you're more likely to spin them i've heard) and make sure you get forged pistons if you're going to use nitrous. With that amount of power you're also going to want to get aftermarket rods especially if this things going to rev. A windage tray is a good idea because all it does is give you free power by keeping oil from sloshing around in the pan and on the crank, making it less likely to airate. Another thing you may want to get is a mechanical roller camshaft (like smoked chevy recommended), the lifters won't pump up at high rpm like hydraulic lifters and roller cams last longer and you can use a steeper cam lobe with a larger lift because it's easier for the lifter to clear the lobe. Roller tip rocker arms are another very good idea, if you don't already have some or if they don't work on your new engine. Another relatively inexpensive idea is a remote filter with an oil cooler so that when you've beating the bejesus out of your car the oil doesn't airate or breakdown from heat, this isn't something you absolutely need to get for your car though. I can't really add anything about the intake/cam combo because you don't specify how high you want this thing to rev or how much horsepower/torque you're looking for and GT350 and smokedchevy said it all. Something else you may want to consider is getting all of your intake/exhaust ports matched/ported and on the exhaust side polished and also some combustion chamber valve unshrouding/polishing with swirl polished valves. How fast you want to go depends highly on how much you want to spend. Good luck
