So since good used 6.5 blocks are getting harder to find and the Chinese new blocks are out there, wouldn't it be better to get a Chinese block and machine it how you need it and then have it hardened?
I have been thinking, the cranks are already hardened aren't they? Are you having that done also? Are you having the cam and rod bearings done as well? If so won't that make the cam bearings brittle? I am picturing them breaking when installing.
So you think it could be in the tow wiring? That is easy to check for open wires or anomalies visually. If there is nothing plugged into the tow wiring how can it cause a problem with the regular wiring?
