The twin V groove won't work for the LS motors. You can have it switched to the serpentine style. If you are using the factory engine acc and brackets, you will likely need to use an aftermarket compressor bracket- either Kwik or Holley- 2 that I am aware of. Either of these will allow use of the factory acc & crank pulley, using one single serpentine belt to run everything. This is a pic of the Kwik bracket on an LS1 with F-body acc. Not an LS3, but similar setup. Scott
