If You think the timing is close, 1st thing I would do is compression check it to see if anything is funny in the valve train. 8)

220 lbs on all 8 cyl??? I would pop the valve covers off and see if any rockers are loose to indicate a prob with cam or lifters.
My 468 chevy was popping through the exhaust, I took the valve cover off and found about a quarter of an inch valve lash. This was the result of a broken lifter that wiped the cam lobe...
