Hey guys I have a quick question, will an LFP quick change lower hub / pulley setup work on an NA 5.4 crank pulley?

also do I need different length belts since I will have an HD upper pulley?

The pulley will bolt up fine. The only concern I would have is that the LFP (and all other aftermarket lower pulleys) have the hole in the middle to compensate for the threaded boss the stock blower pulley reverse threads into. In my opinion, that provide some strength in regards to side load on the pully itself. I'd try it but I'd also check the bolts regularly to ensure they aren't being backed out. Personally, I'd find a stock Lighting lower and use it. They are cheap and should be relatively easy to find used. This is exactly what I will be doing on my S'Crew when I convert it from N/A to a stock Eaton.

Not sure of the belt size you will need.
