I had this problem when I still had the Stromberg on my '75.
You likely have an exhaust leak at the manifold. Mine was the junction
between the manifold and the pipe, you probably have a Cat in that
spot. The design of the intake is such that exhaust gases that leak at
that spot get sucked right back into the air filter.
