Let you know as soon as I get it on though. 
Pulley or not to pulley?
Pulley or not to pulley? Searched & found some stuff, but, would like to ask this way. Already have heads, cam, intake, & exhaust. Will changing the pulley be beneficial in addition to my other mod's.? If so, are they all harmonically balanced? Any recommendations? Thanks.
An underdrive pulley is a great mod in my book. You should get a solid 10rwhp whether your engine is stock or built. Mine works great, with no issues. It's just another piece of the puzzle. 
ROCNDAV,
Yes, that's what I was asking.
Redneck Z,
I see you are using a Powerbond pulley with no issues. Are they balanced?
Blacker,
Do you have a part number? Your 98 is likely the same as for my 99 LS1. Thank-you.

Thanks for the help everyone. It is appreciated.
I have the slp pulley. It's about the same weight as stock , but it's got tall walls so the belt can't walk. Also has very deep groves and looks sweet. I wasn't about to wait 2-3 months for an ASP or march, so i got the slp and am happy with my choice.

Great mod for the money, will help your accessories by not spinning them as fast at high rpm, also picked up the most power for my money of any other mod I had.
