Speaking of dual carb conversions, etc, what, in listers experience, is the
primary cause for the loss of horsepower on later B's? I know there is a
change in carburetion, addition of an air pump, and a cat converter. Is
there anything else? What is responsible for the lion's share of lost
horsepower? I assume it is "breathing" related because very little torque
is lost, but hp peaks at a lower rpm (and the peak is less).
