The timing for the 1977 225 slant 6 cylinder should be set at 2 degrees before top dead center. This applies to both the manual and automatic transmissions.
Place timing marks dot to dot using a straight edge from crank center to cam centerline
6 to 8 degrees before top dead center.
I get nine mpg on the road with mine.
The timing is 2 degrees before top dead center for a stock 400 cid. At least, that is what it indicates on my valve cover. My truck is a 1977 W200 with a stock 400 cid engine. Because of changes in the composition of today's gas, over what is used to be when that label was glued to my valve cover in 1977, many have suggested that it would run better if the timing were advanced a few degrees. Others have said that the carb should be recalibrated as well. Hope that helps.
