True Edelbrock doesn't have a power valve...it wasn't mentioned in the original post and both Holley and Edelbrock have the part number 1406...so it was just a thought...One other thing you could check that could cause this if fuel delivery isn't the problem...check your ground cable from the engine to the frame...run a heavy gauge wire from the block to any area of the truck that has a clean ground...see if the engine doesn't perk up. Often these problems can seem overwhelming when they are something very simple...like a ground wire...I know you mentioned it...Have you tried it?
