Suggest a Nitrous cam for 300 shot

Currently, my solid roller is 248i/254e, 61X is lift with 1.6 rrs, on
114 LSA. I run a Turbo 400 with around 4000 stall. I would like suggestions about what cam I could upgrade to that will love a big shot (300) of nitrous. Keep in mind that I am not concerned with drivability but cam shaft must not rev past 7K (stock pcm issue).

Depending upon what head you have and how good it is. I am thinking about something more agressive but conservative nonethless. maybe 260 @ 50 int, 270 @exh with around .650 lift both sides on 110 LSA. Keep it narrow so the cylinder presure doesn't get to great at low RPM. Let it rev. It will make power.
