I have a o3 5.4 expy. My ? is if I bought the lightning supercharger does it just bolt on with a belt change or is there other things i need to make it complete. I saw on ebay a supercharger for a lightning and its just the manifold with that pulley on the end so i was wondering if thats really all you need. Thanks in advance. I saw other post about superchargers but i'm a little confused cause it looks that simple when you look at the photo of the manifold.

 

You need other stuff along with your computer being reprogrammed...Jonny Lightning will probaby cherp in and state the pistons will not hold up as they are not forged but others have sueprchargers on stock pistons...Do a search and question them...I'm in the same boat as you and want to superchgarge my 03 5.4 but have not decided on either a lightning charger or go the centrifugal way...
