I know these posts are a little old but it came up when I googled it. After reading the posts I went out and checked my 383 fury with edelbrock manifold and holley 4bbl. Started it up and let it run. Carb never got hot-maybe a little warm but not bad. Noticed immediately that the secondaries were leaking gas...drip drip drip. Gonna pull off the carb and check the body gaskets by the butterflies and change em out. Fortunately with holley you can adjust the floats from outside the carb. Turned the secondaries all the way down ran it again and no leak. Seems to have nothing to do with getting hot just a leaky carb.
