Fuel delivery problem, running the float bowls dry.

You have 74 jets in the rear, are you running a power valve in the rear also? That is a pretty small jet. If you are running a power valve could you be uncovering it? Did it always do this? If not have you checked float level in the rear? Why would only a couple of plugs be black, bad wires or bad plugs? It might take a little more info on your part.
