I already put a 650 edelbrock carb and intake on it. Im going to be going through it soon and i want to put a new cam in it, i want to know the stock profile so i have a base of reference in picking a new one. I dont want anything crazy, as i am not rebuilding the bottom end. I cant use 440 cam specs as a reference because the 383rb has smaller intake and exhaust valves, so i guessing the cam profile is different as well.
The next question is why would you need to replace the cam? The valve sizes are minimal and will not be a problem. Does the cam actually need to be replaced?
