From what i've read the pulsation issue happens around 6 times out of 10 for all ls1 owners. It happened to my hawk and i just replaced it with a brand new Cardone alternator and the pulsation completely halted. If i were you i'd drop the stock shitpile and go new so you dont have that problem again.

Relaspe Hopefully I do not have the issue anymore with the rebuilt one. Tried a remanufactured one once but the main power post was screwed up. talking to the place that rebuilt mine and they said a lot of places that remanufacture them use cheap stuff from china. My place only uses made in USA stuff.

i just for go the underpowered stock alt and go get a used tahoe or escalade 120amp alt and never have to worry about it again. forgot the part code for it but i believe its a 2004 tahoe alternator that fits right in there with no modification. i had the same problem and when i did my K-member swap, i put it in there since i had to take it out anyway. Theres a writeup if not a sticky on it somewhere around here.
trust me, this route is way cheaper then going ot the parts store and getting an expensive underpowered alt when you can get a GM stock higherpowered Alt for cheap.
missed the post up top.
K3G is the part number.
