Here are the factory specs. But like I say, if you use them it will not run right.
Modern fuel takes much longer to burn and the engine will need more initial timing. Probably at least 12-14 degrees initial. But then you have to make sure the total mechanical timing does not go over 34-36 degrees.
I would reckon on 12deg BTDC at 800rpm on an automatic with the vacuum disconnected..................but, you are far better off following Daves instruction on setting timing at the top of the Electrical section , its very informative and easy to follow
