We were talking about the cracks and difficulty of fixing cranks, and the cost of cranks and so on. He was telling me how if cracks run a certain way they're easy to fix and how cracks in the main tend not to do that. He got a light in his eye and said - hang on, let's check this out - grabbed the crank and went back in the shop and went to work with the die grinder. A few minutes later he called me back. It turns out the cracks aren't hidden behind a counter weight, don't look to deep and aren't going in the wrong direction. It may be repairable - he's going to do some more grinding and analysis and let me know what it looks like.
The deal's weird - the crank's not bent - it's got less that .001 runout on all journals. There's no cracks in the rod journals, yet the 3 center main journals are cracked.
I'm beginning to think that early hemi's defy all common logic.
