I actually think the cranks are the same too, I believe it's something along the lines of 01+ up N/A engines have forged cranks from the factory. So i guess were both correct? 
Maybe someone can chime in on that claim. Take mine with a grain of salt.
Here is a dyno run before fixing a few vac leaks and porting the plenum and blower. On hot days i make around 11# boost, on cold days I make well over 12#. I use a #4lb lower. Also that break in the curve is my torque converter. It's old and tired
I'm making a bit more power now, cant find the other sheet.
Are you running a KB on a stock N/A block?

I thought all 99-04 lightnings had a forged crankshaft?

The lightning motor is NOT all forged. It is lower compression but it's not ALL forged. The rods are the same as a N/A.
You will need:
Airbox
90MM MAF
Intake Elbow
TB w/ cruise control/throttle bracket
Cruise Control & Throttle Cables
Plenum
Blower
Mid Plate
Intercooler
Lower Intake Manifold
Intercooler Reservior
Intercooler Pump w/ brackets
Intercooler Hoses
H/E w/ bracket
Crank Pulley
Belt
Blower belt tensioner bracket
42# injectors
255lph fuel pump
Alternator
Alternator Bracket
EFans or Waterpump spacer
Misc bolts and hoses but for the most part that's it.
I have done 2 L blower swaps and work on L/HD a lot so if you have any questions feel free to PM me.
Check out Madenterprise.com for a even more detailed list. But there are a bunch of things in the list you don't really need.

I’m putting a 5.4 Lightning motor into a 2003 f150. I have all the mechanical done but am running into wiring issues. I bought a lightning harness but it won’t plug into the cab harness more are their places to relocate the wires to at the wiring block. Where should I go from here?
