More than likely the chain/gears are the problem since you had problems prior to the swap. But you don't need to worry about messing with the vac adv rather it's ported or manifold. It is NOT needed for idling purposes. If you just plug the hose from the vaccumn source your are eliminating one potential problem variable which would be an issue either with the distributor itself or an issue with the vaccumn source ported or continous. Your carb could be way out of wack in it's adjustments etc etc. That is why I mentioned about doing a compression test to at least make sure you have good cylinder pressures. Whatever reading you get, they all should within 10% of each other.
