I don't remember, but HDDP knows who does, either he purchased some or almost purchased some, I think at a substantial discount as well. I once linked us to a group buy for the cams once before from MBworld.com, but as usual, no one jumped on with me. Go over to MBworld.com, join and search, you will find a ton of mods for your car. The v8, like the v6, responds very well to ecu modifications ( i picked up 19 whp with the ecu mod) so if you get the cams and an ecu mod you would probably pick up 40 whp or so. I remember reading (but could be very very wrong) that ths v8's picked up 25 whp or so with the shrick cams.
