No, it uses the same belt. It's a LONG belt. I found one that is the EXACT length needed and it's a booger to get on, but I had NO belt slip what so ever with it.
The kit comes with 39# injectors. Ill throw in some HTO spark plugs, and clean the K&N filter. Ill try and make sure I give you all the zip-ties you need also.
I will give you everything you need that gave me my 450/450 tune except the fuel pump. You might not even have to buy a fuel pump and just buy a boost a pump. You can find them used on SVTperformance forum from time to time and save you some money.
Ill also throw in(if I can find it) the original 9lb pulley. You shouldn't have to worry about a fuel pump/boost a pump then and still make some good power on a good custom dyno tune. The torque(boost) just won't come in as fast. I highly recommend using the 12lb pulley as the boost comes on much faster.

Use the 12lb. The 12lb is where the bottom end torque would come in, which is what your screw would need. I would highly advise against anyone from going lower then a 12lb pulley with a centri' unit.
If you read in the supercharger section, there is a discussion of using that 12lb pulley and a 4-6lb lower with a waste gate to achieve awesome horsepower and torque numbers.
These 5.4 engines are plenty safe on 12lbs, even more actually... I have already met a few guys running 15lb's on stock bottom ends, and have for a few years.
Daily beater...
My truck keeps getting chips and just daily beating up... I want to retire it from the daily grind.

how long would this kit take to put on? do you still have instructions? I've been looking for a shop that might be able to tune it in, what does a guy look for or how do you find a good dyno shop, I am in the se MN area so if anyone has suggestions
