Good food for thought here and I thank all. As far as the possibility of simply lugging the engine, would that create the dieseling noise I described (it sounds like scattershot pinging)? It does not seem to happen when I hard accelerate from say 3,000 rpm....

about the lugging, the noise i'm familiar with is a chugging, bucking, stumbling sound, rather than bbs in a coffee can.
since lugging only happens in 2nd gear and up, you could check the lugging theory by briskly accelerating (like you did before) from a standing start in 1st gear. if it DOESNT diesel below 3000 rpm, i'd guess your earlier experience below 3000 rpm was just lugging. (i'm assuming your earlier runs were in 2nd gear and up.)
about your ignition timing, there's a good discussion here

the discussion is about a 1983 SC, but i understand the timing is the same for the 1980-83 USA cars.
