The biggest problem with an Ebrock in a single, NON TUNNEL RAM application is heat soak , even with the heat riser blocked , the crap fuel we have today will literally boil off while you are driving it.
john, i haven't found any difference between a holley or afb when it comes to heat soak. on my junk they both have/had heat soak issues. the only solution i found for either carb was a fiber insulator gasket, and winter blend fuel really ups the tune-up misery factor for either carb.
