I have a complete 07 M6 motor disassembled. A rod bearing went out and I do not think there was any crank damage but dont know for sure other than visual evidence. The case is good and I have PV with Cables, ECU, Harness, Cylinders (Cores) if you had m6/ M7 bottom end would bolt together. PM me if you have interest in any all listed or not listed M6 Motor parts.
