Aha! This is something I've read about. I don't have the ref. to hand, but one piece of info about Saab's own blocks was that they were in fact made of cast carbon steel, not cast iron (the main difference being that steel has a lower carbon content than cast iron). This is more expensive than the mainstream cast iron production material, and was (is?) used by only a handful of manufacturers. It makes the blocks significantly tougher. -- Grunff
