1987 Chevy Monte Carlo V8 Two Wheel Drive Automatic

I recently rebuilt my Chevy 350 with all new top end components, with a decent sized cam. The problem is that it is hard to start some times and runs rough until warm. When at cruse the engines feels like it is misfiring or hesitates, but under accelartion it runs fine. I have replaced the spark plugs, but still has the problem. Was wondering if was either an ingition problem or possible carb problem.
