Im a dummy when it comes to this stuff

[DBYRD]

k u guys know by now that for the most part im a window shopper. but i was on summit looking and it shows an under drive pulley, and harmonic balancer as upgradeable parts. my question is what do these pulleys do to help performance, and also, do u have to change anything else if u buy these? im a dumbass i know, but can someone explain. also is there any other pulley upgrades on a stock 364(6.0 LQ4) or r these the only two?

underdrive pulleys are less rotating mass and therefore more usable power. I've never used them though, but someone who has can tell you if they actually help. You might have to buy a smaller belt, but i don't know.

Smaller belt for the UD and Alternator Pulley.
The manufacturer's website will tell you what belt size for what pulleys you put on.
I have ASP's and i bought them from Speed Engineering.

I haven&#39;t sued them, but from the research I&#39;ve done and what I&#39;ve been told, I think they&#39;ll net anywhere from 3-8 rwhp. I could be off, that&#39;s just what sticks in my head.
