wanted 4bbl carb and intake

i am in wilson nc 45 mi east of raleigh, if i am reading this correctly i will be better off with an aftermarket intake and a holley 600 (which I was going to choose) but I do want a factory 4bbl aircleaner to ride on top, about the cam , will that add a rumble to the car, i want the engine to sound smooth. My dads 67 cuda has a 360 with a cam and at an idle it rattles the fillings out of your teeth, this i dont want.
