I went ahead and changed the timing chain and gears reset the timing lined up the circles on the timing gears. Took the driver side valve cover off and watched the valves open & close to find the compression stroke. when the number one was TDC on the compression stroke the circles on the crank and cam gear was at 12:00. I put the distributor back in with the number one wire at 5:00. When I cranked it up I had the very same problem, I was able to advance the rotor to the number one plug to about3:30 and the timing mark is behind the water pump. The motor runs the best with the mark at about 11:30. There is still a good rumble out the exhaust and I only get about 14 lbs of vacuum. My vacuum meter says delayed timing?????
