If you lost the three tenths between the last week of June and the first or second week of July, consider the radical weather change. If you were jetted a little rich last month, you are way too rich in the oppressive gunk we've had for air this month.

Change your metering rods, and you might regain half of what you lost.

Have you been logging your air/fuel with a wide band? You should do that, besides tuning it's a good reference when something like this happens.

I had a very similar problem many years ago with my 71 Duster stocker. Changed everything, ignition, fuel system, trans, convertor, etc. etc. Nothing I did made any difference so far as being faster or slower. Turns out the 8 3/4 rear end housing had bent after MANY years of use and abuse. I didn't have a brace welded on at that time. The way I found it was I was going to install my spare hogshead to see if that was the problem. It was near impossible to remove the axle shafts. It might be worth looking at.
