excess positive camber 440 A body

I don't think that I have it backwards. I think you read it wrong. When the toe is in too far, forward motion of the car wants to jack the front up in the same way a snow skier points the tips of the skis together to slow down in low speeds. This causes the front to rise and the camber to go positive. The opposite is true as well. Too much toe forces the tires rearward while making the suspension want to compress.
Maybe we are saying the same thing but with different words?

It appears so!
