My 04GT has been swapped with the equivalent of a 96 cobra motor (97 mk8 long block, sn cobra cams, parts, etc). I just picked up a vortech v1 kit for it, and it has an 8 rib pulley. I know I can run a 6 rib belt and not bother converting everything over, but I'm considering going 8 rib. What pulleys do I need for the AC compressor, PS pump (running the OE 04 GT pump), tensioner, and idlers? The others were included in the kit I bought.
