I am not sure what physical size the gas converter is but what I am saying is a diesel converter will fit inside the bellhousing since its the same bellhousing found on a 5r behind a 6.0.
This is interesting. I have a 4r100 out of a excursion I bought for a core turn in but never needed it. So this could be built, an used with a trans adapter plate and bolt up to a 6bt and live well to 600-700hp?
