Engine shakes BADLY!!

If it's rough at idle and smooths out with rpm, it's cam and carb. Lumpy cams need more are in the idle circuit. There is only so much you can do and if the cam isn't properly degreed, it only aggravates the problem. I've had an out of balance problem before. It tends to get worse with rpm. Your initial timing is higher than I like but if it starts fine I bet it's responsive.
