Went over to pick up my mailbox post from the crank shop yesterday...
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.
