Also, don't forget the MAS conversion. Without it, the truck will sound like a blown alcohol engine, always serching for an idle. There are not many off the shelf cams that are SD friendly. The Crane Lightning cam seems to be very good, but if you want roller, then you'll have to get a custom ground cam that will work with SD.
