need a cam. which one? help!

i built a 360. i run pretty good. the engine builder told me the cam i picked is a little small for the heads i got. i was thinking of changing for a bigger one. i need help deciding on the best cam for my setup to make the most power. please help me out and give me some options. mostly street driven duster, 727, 373 dana, im getting a good dynamics stall soon somewhere between 3000-4500 stall.
