Catalytic Converter on a 65 Slant 6?

The sun rises in the East, even for those who don't believe it.

Dropped items fall down, even for those who don't believe it.

And even for those who don't believe it, burning a U.S. gallon of gasoline creates 20 pounds of CO2. Doesn't matter whether the gasoline is burned in a '61 Valiant without a catalytic converter, in a '21 Chrysler Pacifica with a full brace of up-to-the-minute emission control technology including a catalytic converter, or a metal pan on a concrete sidewalk.

None of this is political or debatable.
