Udp?

Udp?
Im thinking about a 25% UDP for my birthday in a couple weeks, but Im running into a little confusion. My LS3 has the vette front drive setup. Am I right in thinking the c5, c6 LS1, LS2 and LS3 all have the same offset on the crank pulley and interchange? That's what I am gathering by my research, but Summit doesn't show the C6 LS3 on the app chart. It just goes up to the 06 LS2.

I don't know the answer to the offset question, but I have read from some engine builders who say do not use the 25% pulley. If you have to use underdrive, use the 10%. The 25% supposedly does not have enough mass to effectively dampen the harmonics.
I have the Vette accessory system on my car, but it was the LS2 style. I would think they are the same, but I am not sure.
Oh, and one more thing, ATI for the win!
