Haven't been on this forum in a while so I am not sure if this has been discussed in the past few months.
Back In February, Cummins unveiled their new fuel-agnostic strategy meaning that various engines in their line-up can be spec'd for different fuel types like propane, natural gas, hydrogen, and yes even gasoline. To clarify, that doesn't mean that one engine can run on all of these fuel sources, but rather you can have them spec'd to run on one of these fuels only and not just diesel.
These engines will share 80% of their parts. From the head down these engines will be mostly the same as the current Cummins diesel. From the head up you will have different parts to for the various fuel types along with different fuel and air delivery systems. So essentially you will have the same reliable diesel engine components, but in gasoline form.
They said that the B6.7L will be the first to be offered with its fuel-agnostic strategy in 2024. Medium duty customers will be able to spec the B6.7L to run on gasoline. I am not sure what plans Ram has for the 6.4L, but I would love to see a gasoline powered Cummins 6.7L turbo in a Ram HD. Not sure how they will handle the heat associated with gasoline turbo engines.
What do you think?

With today's prices, I am not surprised anymore on what people will pay for stuff. Many will lay down $11k to go from a base trim package to a premium without batting an eye.
Although I don't think this would be nearly as expensive as the Cummins diesel. You would not need a lot of the emissions equipment which would reduce a lot of cost and weight. You would also not need iron heads, a VG turbo, as large of an EGR and fuels system. So there could be a lot of cost and weight savings in a gas version.

There are a lot of turbo gassers out there. They do tend to be on the small side but the drag guys are building dual turbo big block hot rods also.
I think it's good that Cummmins is thinking ahead to the future. We'll see what fruit that tree bears.

I bought a herd of Kubota diesel engines converted to casing head gas, to power pump jacks on oil wells. Honda gasoline engines just self destructed. They did not have enough cooling in the heads. They were designed with the evaporation of gasoline in mind for some cooling. If your ran them at max horsepower, they just could not cut it.
So, they might have a market, but I don't think it would be real big. Interesting though, assuming you get Cummins support. Would truck owners buy a gas engine, at diesel engine prices???

It sounds like there's a lot of common parts on these engine configurations so there was engineering cost savings, tooling savings, and I suspect all these engine configurations will be produced on the same assembly line as the diesel engine so that should equate to more savings.
So overall less investment and operations costs to bring these engine configurations to the market should mean a less expensive engine.

Wouldn’t the fuel economy of a 6.7 turbo gas engine make almost unaffordable?
