In my 360 I ran Comp Cams XE262 which is close to the 6900 cam you picked(but more lift), there was a slight lope at a low idle, I changed it up to a Comp Cams XE274 and that is close to the 6901, (again I think it has more lift) and I have a nice, quite noticible lope.....actually way to much for any streetable, daily driver truck....but it does sound great and works great with headers and intake, if you choose this get a 2500 stall convertor as well....but say goodbye to fuel economy as you will have your foot into it all the time....
