The timing marks are on the Zero mark down on the oil pump. Its seems when it was timed before the distributor was almost all the way turned in towards the firewall before it would read time at -5BTDC. But with the new way the timing marks are, there seems to be two legitimate options of how to put the distributor in as opposed to one that was at 12 o'clock and one that would go in way off if that makes sense, but like I said I don't want to run it until I get some more feedback?
