305 Quadrajet Rough Idle

Hey guys I am having trouble with my car idling rough. It is a 305 with a very mild 274H06 Cam in it. I have to have it idle at around 1000 rpm and when I put it in gear it slams down to about 600 and the car will literally shudder and shake. I have adjusted timing and idle fuel mix to no avail. You guys have any idea on how to smooth this thing out?
