You do know there is an engine section on this forum right?

What? Engine section? What's an engine? Wouldn't this go in the pulley section?

Daniel, I believe the ASP's have the largest underdrive. Your best bet is probably Summit. Gains are minimal compared to stuff like cams and headers, but they're gains nonetheless.
I believe HitManX sells the ASP pullies for a great price if you're not in a huge hurry for one.

i hear that UD pullies don't work that well with the 6.0. and alot of the people on the silveradoss forums has had problems with em and i was advised to stay away from them. they are better on the 5.3's and 4.8's. and plus, you get very minimal gains for the money your spending.

Mods- Wheatley Tune, 160* Stat, Zippy Shift Kit, Trailblazer Stall, Tru-Cool Cooler, Volant CAI, Corsa Sport Catback, Jet-Hot Coated Pacesetter LT's, High Flow Cats, Precision EZ Solid Grill, tinted taillights & windows, antenna delete, chrome SS bowtie, stainless bumper duct surrounds
Future Mods- Goodmark cowlhood, E-Fans, P&P TB, and more bolt-on's. (if there is any left)
There is NO difference between the 4.8, 5.3 and 6.0 accessorie wise to make the 6.0s not work. Im running a 420 with an ASP pulley and no problems, its a 6.0 block just like the SSS trucks. Point blank UD pulleys barely give you any HP its one of those things if you have the money and can get a could deal on them and have all the other bolt ons covered then do it.
