Here is a guy who got 393hp to the ground.
http://s197forum.com/forum/showthread.php?t=51113

393rwhp/334rwtq.

Mods:
Steeda 90mm CAI
Steeda UDPs
FRPP Cobra Jet Throttle Body
FRPP Intake Manifold
FRPP CNC Heads
BBR Stage 1 billet cams
BBK 1 5/8 long tube headers
Hi Flow catted X-pipe
Roush axle backs

I can imagine if he had a bigger cam he would be in the 400's easy.

The first 3 items including a CAI will put you over $1700.....let alone the rest of the list.

That'll get you mid 300's. Gears don't need to be on the list, aluminum drive shaft should be. To approach 400 NA on the stock bottom end, heads will be a necessity.
