The 2.3 has never been an interference motor. Their information is wrong.
The block never changed since it was employed as an engine in the Pinto. The heads changed combustion chamber and exhaust/intake port design over the years, but the physical heads stay'd the same size and basic design up through its days. This includes the 2.5's as well.
The valve train never had a cam big enough to dive deep enough into the cylinder to pose an interference possibility.
The Lima platform evolved over its ~30 year life span, from the 2.0, 2.3, and 2.5, but never once was it an interference motor.
Going back and looking over that chart, I'm betting they are concidering the 85/86 deisel 2.3 in the ranger to be intereference. Which may perfectly well be, I know nothing about the 2.3 deisels that Ford threw into our trucks other than I know they were still Lima based and I thought they were just modified gas motors to be deisel compliant, and in doing so this may have created issues where an interference valve train could have been a possibility.
