Default Newly rebuilt 427 engine stumble

Let me see if I can explain this correctly. If i'm cruising at 1500rpms and put the peddle down I get a slight stumble before it picks up. I thought it was because of the carb not being set up right. Took it to the garage checked eveything out he said the power curve on my cam was higher then what I was trying to have the engine do. Now without going into all the specifics of everything has anyone else had this issue?

I you cam has enough duration the motor will not run well at lower rpm. My 427 really doesn't run that well below 2000 rpm.
