I've run a holley/weber from langdons stovebolt on my .060 261 with no problems for 5 years,got good mileage on the highway with it. Just recently changed to a later model rochester monojet and the improvement in response is nice and smooth, the engine runs great at low, med., and high speeds. However the milage has fallen off a little, but that may be because my foot is into the gas pedal a little more.
