Personally, I like the 068, good performance and near stock idle. Though the 400 I have with it is set up with 1.65s.
Are you willing to give up some idle and vacuum for 20-30 hp gain? If so, I think the 2802 or the 60916 is more of what you are looking for. Little to no gain over the 068 with the 60242.
