You got it! But you may have to add bypass air to control the idle quality and speed as well. The bigger the cam, the more bypass it wants.
I have had a 270/110 cam and it didn't want much bypass. I have a manual trans tho, and so I do not have to compensate for the TC dragging the idle down, when put into gear.
In post #9 you gave us a video of the idle jumping up and down some 200 rpm. This is usually called surging. It is very often the result of a fault in the power-valve system. For your Eddy this means, in all likelihood the metering rods were not staying down. The springs were too strong for the amount of vacuum the pistons were seeing. The most logical conclusion I came to was a large vacuum leak.
