LD4B how good and how rare what are they worth?

IMO, they (along with the LD-340) are a (often ridiculously) overpriced antique part that gets outperformed easy by modern easy to get parts.

The regular RPM for an everyday driver, an AG for a engine designed to be more aggressive street - street/Strip car.

As title says. I’m curious how they compare to the new Eddy RPM and Airgap. What are they worth these days?
