Rebuilt 360, excessive oil consumption

A little more information, when driving down the road, I can not see any smoke, but when I "punch it" a good bit of blue-black smoke rolls out of the passenger side. And this is only after driving at a steady rate for a time. As for the plugs, the fouling got worse toward the back of the engine. The #8 was by far the worst. It was the first one I took out, and it was almost completely shorted out. I chipped a lot of the crud off of it before taking the pics. As soon as I get time, I am going to run a compression test.
