4.6 Mod HELP!!!

Hey,

My dad recently bought a 00 GT and wanted me to set up a combo for him, and i was wondering what you guys thought about this combo and what it would be worth in ET/MPH (on Drag Radials) and also in HP/TQ

00 GT Plans:
Vortech S-Trim
Port And Polished Bullet Intake
Port And polished stock Heads with bigger valves
70mm TB
80mm MAF
Timming Adjuster
Adj. Fuel Regulator
Injectors/Pump
Headers
X-Pipe
FLowmaster Mufflers
Saleen Suspension
Pro 5.0 Shifter
3.73 Gears
Air Locker on Rearend

What else do i need? What kinda problems could i run into with this combo, Thanks for any info
