Car has done just over 1,000 miles now, which is notable not only because it's done barely more than that in the last three years, but also because it's only taken four tanks of gas. 
*Much* better fuel economy since the swap, mid to high 20s pretty reliably where previously I was averaging mid teens. In the car's defense, I'm sure a lot of that poor mileage was a result of running an LoM carb without an LoM distributor. I probably do 60-70% surface street driving, since the 2-speed auto and 3.50 rear end isn't much fun on the freeway. That's about 3400rpm.
Anyway, I pulled the plugs yesterday to replace them with iridium plugs. More experimental than anything else - I figure these plugs do well on other cars with similar ignition systems, so I wanted to see what they do - if anything - on the Falcon.
The plugs than came out have around 1,500 miles on them. 500 of that was on the old ignition and they did NOT look pretty when I fired up the EDIS. Quite black from an obviously rich mixture. 1,000 miles with a modern ignition system actually cleaned them up quite a bit! There is some baked-on carbon, but otherwise they look quite healthy to me! They are NGK V-Power (copper/resistor) plugs.
