Motor Build Ideas and help???

Hey Im planning on rebuilding my motor next semester in my engine class im taking. This is gonna be my 2nd motor i build from the ground up and my teacher whos been building engines and racing for like 40 years is gonna be helping me. I have a 350 right now and plan on spending around 5-6k for everything. I will be doing all the machine work myself with the teacher as the school has good equipment so i wont have to pay for machine work. I want to have hp somewhere in the 700 range at the flywheel and rev out to 7000. I will be doing the neccessary precautions for this hp, I already have a 12 bolt rearend, and will be getting a turbo 400 as well, and all the suspension work to go with it. Ok while i have knowledge of how to build a motor i have limited knowledge in cams, different strokes, and general application. My primary use for the car is gonna be drag racing so while i will drive it on the street very very sparingly its gonna be a mostly drag only car so im looking for an aggressive setup and want everyones help and suggestions
I was thinking of building a 383 with an Eagle forged crank and rods, not sure which pistons i should get to handle the hp i want but JEs look a little expensive, and i will be getting a custom ground cam for sure but im not very interested in the idle quality i want domething thats gonna move above 3000 RPM and go till 7000. I was thinking about 11:1 compression and For the heads and valvetrain I want AFR 210s and i plan on upgrading the valvesprings for the cam. For the intake manifold im gonna go with a stealth ram and port it out to match the heads. I was also thinkin about sprayin 100-150hp on it but that might be overkill. My goals are 700 hp and i dont even know what 1/4 mile time to expect with a setup like this. Now is what im thinking the way to go, is a 383 a good idea, 350 better, what other options do i have, what would you guys reccomend for my goals??
Thanks

pay attention to the ignition system. A bigger coil and wire set up will not cut the spark power you need to have 700hp at 7000rpm.

there are alot of different distributors out there try to get one that matches you ignition box.
