I plan on buying some cams very shortly and I want either the detroit rockers or the frpp hotrods. They seems like very similar cams but want feedback from people who have them. I would like to know of any hp gains, any torque loss , drivibility issues and definatly the sound. Some have said the hotrods are louder than the detroit rockers. My gt is an auto btw. So if you could let me know how your experiences have been with them would be very much appreciated! also i have seen other forums talking about the same topic, but they date back atleast a yr or two, but I would like hear more recent feedback, since the boths cams have been out for awhile.
