You don't need a new cam. I have a very similar combo that made 309 on a Dynojet @ 5800 rpm. I think you have something else wrong. Has your car been to the track? If so, What are it's trap speeds?
Falling off at 5 grand could mean a whacked out air/fuel ratio, mis adjusted valves, bad valve springs, improperly installed cam, just to name a few.
