This truck has what Jerry called a Stove choke in the exhaust manifold. The plugged holes must have worked their way out from use. The tube that runs up and down was gone. I plugged them both and the performance is very notable. If the tube was in tact , there is no effect on the engine. The hole runs from the top diagonal to the bottom. About 10 inches. Ram horn.
