neither of those pics are what you get for an LS1, its close to the second pic but the blower pulley will bolt to the front of the damper.. The SDCE pulley will bolt to an ATI damper, the stock procharger lower will not. But the 8 rib procharger pulley will.
Confused yet

The serpentine pulley for the alt/water pump/PS is made onto the damper itself, it depends if you want the a/c pulley or not and if you want 10% underdrive or standard diameter.
Here is mine, its 10% underdrive aluminum shell without the a/c pulley, steel hub (PN 917277) and the SDCE pulley bolted to it. The a/c pulley bolts to the back of the ATI damper. Maybe that will give you an idea of what it looks like..

917276 is 10% underdriven with A.C.
917277 is 10% underdriven without A.C.
Note that these are for the LS engine in an F body. I have them both listed in the store area of my website, as well as the drill kit required. Bob

Just buy the kit from Bob (Exotic Perf) and you will have exactly what you need. And save yourself some headaches & change over to an 8 rib. Also plan on spending a couple hours drilling your crankshaft (for the pin so the damper/pulley doesn't spin).

OK, so the ATI Super Damper is needed for cars that run 10.99 & faster (NHRA SFI rating). The larger ATI pulley will not bolt up to the stock damper, so if you want more boost you need to buy both (since the MMS isn't available anymore). And an 8 rib pulley will not slip & blow off for 6-10lbs of boost like the regular 6 rib does. You will need to get the pulley kit for the s/c if you go 8 rib (it comes with more washers & longer spacers in addition to the pulley).

The ATI is a damper with the accessory drive pulley cut into it, if you wamted A/C that pully bolts to the rear of the damper like the SDCE bolts to the front
