Maybe an other head producer in the game.

Believe what you want. It’s a small market.
How many RItter blocks you figure have been sold in the what, 10 or so years they have been around?
Nobody's arguing the market size but even a blind man could see there are more performance parts than ever for the small block mopar. Bottom line is there are some companies that are willing/making big investments in an engine that you keep claiming is all but dead. I would think you would be happy about that instead of arguing about the futility of it.
