Thats a whole other topic. Thats been discussed for decades, and it was even thought at one time the Toyota Landcruiser engine was the same one, but it isn't. The bolt pattern and bore spacing on the Stovebolts is so unique, it would definately take a lot of ingenuity to pull it off. Most of the european stuff is all overhead cam, so that isn't going to be practical, you are just going to create a lot more stuff to fab and engineer to make that work. The bores on the Stovebolt are not equidistant between each other, so that is going to be more challenging, than if they were equally spaced apart.
