Not that this "means" anything, but I just went out in the shop and looked at various cranks I have for some BBM and BBC engine projects I am working on. The cranks range from a Bryant Billet, a Lunati Pro-Series, an Eagle and 3 Callies. NOT ONE, has a lightening hole in a rod journal drilled at an angle, nor do the dozen or so factory cranks I have sitting around. IMHO, I would NOT run that crank in an engine with decent power. You have effectively weakened the throw into the cheek and that would be a likely place for a break. This is where cast cranks always break and while this is not a cast crank, the crank is most certainly weakened that area. As to whether this is corrected on later cranks....who knows, crap shoot at best. Again, based on what has been seen, YOU MUST CHECK these parts, old or new.
