I haven't tried it but I know the LS3 covers from the vette clip onto the fuel rails. Since the intakes are different you may have issues there. They also have rubber mounts that slip over studs that hold down the coil packs. I'm sure you could mod it to work but I doubt it will be a direct fit. I could be wrong though, have been before lol.
