Jim, still figuring out which model Edelbrock I have. The truck is at a local garage at present.
I probably should have said I'm turning to dealing with the carb after taking care of several other things, including: New ball joints, new tie rods, tightened steering box, new alternator, new battery (one with the proper CCA), new voltage regulator, new air filter, new fuel filter, new plugs and plug wires, oil change and new distributor cap.
