I don't know if this matters anymore but I made some calls. BHJ will make you one with serpentine pulley on it. It will take 6 weeks at a cost of $600. Talk to Chris if interested. They would normally be $525 but since it's their first one there is a $75 set up charge. They made me an SFI damper with serpentine pulley for my blown 292. Mine was $1000 but I had to pay the engineering fees. The next guys will be cheaper. Not for everybody but I thought I would put it out there. 6 rib is a stock pulley but they can do an 8.
