Same drill, stop the distributor on the high lobe and check your points. If they are not opening adjust them so they do. The firing order is the same for almost all chevy motors. Glad to hear you got the Chevelle running. The miss could be timing, carb adjustment, or a vacuum advance problem. You can convert your original distributor with a protronics ignition system. I running that in my Chevelle. It looks stock, but is not. A search on the net will give you info about it.
