To get to 400, you will need a big budget and at the very least:

99 PI heads/intake/cams
Some sort of supercharger, preferably with intercooler
A good tune

Those 3 might get you to 400, but I'd go ahead and do beefier internals and exhaust too. Internals and Longtube headers when the engine is apart, an offroad Hpipe, and flowmasters. That'll be quite a sick stang for sure. Good luck to you.
