Lower Pulley Swaps?

[St_Evo]

I know there are probably a lot of threads on this topic but I havent seen anything as specific as I need. I am running the typical bolt-ons with a Steggy Stg V blower. People recommend that I run a 2.93 upper and a 4# lower. Are there any downsides with changing my lower pulley and also what all do I need to pick up?

LFP? or Metco?
If I have done my research right it looks like I need :
Lower pulley kit... w/ 4# lower
Alternator Pulley - 3.20
Billetflow 2.93 upper w/ hub
How many idlers do I need and what sizes? Also, do I need a snub idler pulley and what size belt?

Thanks guys!

What are you doing for fuel? The 2.93/4lb is a popular combo. I would go with Metco and run a snub idler at the least. Preferably run ALL the idlers, billetflow makes a great piece as well as Metco. Metco and Billetflow both sell a complete idler kit. You will need a 78-79" belt. I prefer Gates.
